Detailed Description

Driver for the DSMIF peripheral on RA MCUs. This module implements the ADC Interface.

Overview

The Delta-Sigma Modulator interface (DSMIF) functions similarly to a normal ADC, however, instead of sampling an analog signal directly, DSMIF samples a PDM signal that is generated by an externally connected 1-bit Delta-Sigma Modulator.

DSMIF Overview

Every instance of the DSMIF peripheral has 3 separate channels that can sample independent PDM signals. Each channel has a pair of sinc filters. One sinc filter is used for normal measurements, and the other sinc filter is used for detecting error conditions. The sinc filter configuration will determine the sample resolution, and the final sample rate for each channel. There are three primary configuration settings for the sinc filters:

Sample Rate - The frequency that the PDM signal is sampled.
Decimation Count - Number of samples that are removed between the integration stage and the differentiation stage of the sinc filter.
Filter order - The filter order of the sinc filter: [1st, 2nd, 3rd] order.

Features

The DSMIF module supports the following features:

Two independent units (3 channels per unit for a total of 6 channels)
Configurable sinc filter (1^st, 2^nd, 3^rd order)
Configurable decimation count in the range (4,256)
Support for master and slave modes
Channel synchronization
Trigger data capture via ELC events
Trigger reset of decimation counter via ELC events
Configurable error detection
- Overcurrent error detection (Can trigger common error interrupt)
- Overcurrent sum error detection (Can trigger common error interrupt)
- Short-circuit detection (Can trigger common error interrupt)
- Window notification error detection (Can trigger Port Output Enable for GPT (r_poeg))

Clock Configuration

The DSMIF conversion rate is determined by the DSMIF Core Clock, A/D Conversion Division Ratio (CKDIV), and the configured sinc filter's decimation count.

The DSMIF Core Clock is common to all channels and may be configured to the following settings:

PCLKA - Peripheral Clock A
DSMIFCLK - Dedicated DSMIF Clock
GPTCLK - Dedicated GPT Clock

The A/D Conversion Division Ratio (CKDIV) is a channel specific setting that further divides the core clock by the following formula:

A/D Conversion Division Ratio = (2 x (CKDIV + 1))

Note: 1. CKDIV is set in the range [2,63].; 2. CKDIV is only valid in master mode.

The decimation count is a channel specific sinc filter setting that will determine the final conversion rate of a DSMIF channel.

Note: 1. The decimation count is set in the range [4,256].

DSMIF Recommended Clock Configuration:

DSMIF Core Clock (Mhz)	CKDIV	DSMCLKn (Mhz)
300	0x05	25
	0x08	16.67
	0x09	15
	0x0E	10
	0x1D	5
200	0x03	25
	0x04	20
	0x07	12.5
	0x09	10
	0x0F	6.25
	0x13	5

Note: 1. If settings other than the recommended are used, there is an additional clock constraint: DSMIF Core Clock/5 ≤ PCLKA

Pin Configuration

Each DSMIF channel has two pins:

DSMmCLKn - DSMIF Clock Input/Output. In Master mode the clock pin is an output, in slave mode, the clock is an input.
DSMmDATn - DSMIF Data Input.

Usage Notes

Channel Synchronization

Multiple channels may be optionally synchronized in order to generate common interrupts in response to the following events:

The following sets of channels may be synchronized:

Channel 0 and Channel 1
Channel 0, Channel 1, and Channel 2

When synchronizing channels, each channel must use the same 'Clock', 'Filter', and 'Trigger' configuration settings. For convenience, channel configurations can be reused between channels of a DSMIF instance instead of creating new channel configurations for each channel.

Note: 1. Channel configurations cannot be reused between different DSMIF instances.; 2. Channel configurations can only be reused between channels that are synchronized.

Filter Settling Time

The filter settling time is the time required for the filter results to be valid after the DSMIF channels have been started. The settling time is determined by the DSMCLK period, Decimation Ratio, Filter Order, DSMIF Core Clock period, and Peripheral Clock period.

The following macros are generated by the tooling in order to assist with determining the required settling time:

/* Calculated settling time required for DSMIF filters (See "Settling Time" section in the MCU user manual). */
#define DSMIF0_FILTER_SETTLING_TIME_SYNCHRONOUS_US      (...)
#define DSMIF0_FILTER_SETTLING_TIME_ASYNCHRONOUS_US     (...)
#define DSMIF0_FILTER_SETTLING_TIME_GPT_SYNCHRONOUS_US  (...)
#define DSMIF0_FILTER_SETTLING_TIME_GPT_ASYNCHRONOUS_US (...)

Note: 1. For more information on how to calculate the settling time refer to the MCU user manual.

Error Detection

There are four different types of error interrupts generated by the DSMIF peripheral:

Overcurrent error detection - Triggered when a conversion result exceeds a configured upper/lower limit on a particular channel.
Overcurrent sum error detection - Triggered when the sum of conversion results from a set of channels exceeds a configured upper/lower limit.
Window Notification error detection - Triggered when a conversion result falls within a set of configurable ranges.
Short-circuit detection - Triggered when a configured number of consecutive '1's or '0's are input on a DSMmDATn pin.

In order to enable error detection, the application must call R_DSMIF_ErrorDetectionEnable after waiting for all DSMIF channel filters to stabilize. The amount of time required for a filter to stabilize is dependent on the filter parameters, and clock settings. Refer to the MCU user manual for determining the filter stabilization time.

Once error detection is enabled, R_DSMIF_ErrorStatusGet can be called to read the error status.

Note: 1. Error detection is disabled when channel operation is stopped via R_DSMIF_ScanStop. When starting channel operation again, the same settling time is required before reenabling error detection.

Error Interrupt

If the error interrupt is enabled, the following configured error flags will generate an interrupt request:

Overcurrent error detection
Overcurrent sum error detection
Short-circuit detection

Note: 1. Since the error interrupt is a level interrupt, R_DSMIF_ErrorStatusGet must be called from the user callback in order to clear the associated error status flags.; 2. Window Notification error detection does not generate an interrupt request.

Limitations

Developers should be aware of the following limitations when using DSMIF:

The DSMIF peripheral must be stopped prior to entering software standby mode.
