Detailed Description

Build Time Configurations for ra4w1_fsp

The following build time configurations are defined in fsp_cfg/bsp/bsp_mcu_family_cfg.h:

Configuration	Options	Default	Description
Enable inline BSP IRQ functions	Enabled Disabled	Enabled	Using static inline functions will slightly increase code size, but will slightly decrease cycles taken in ISRs in return.
Use Low Voltage Mode	Enabled Disabled	Disabled	Use the low voltage mode. This limits the ICLK operating frequency to 4 MHz and requires all clock dividers to be at least 4.
Main Oscillator Wait Time	2 cycles 1024 cycles 2048 cycles 4096 cycles 8192 cycles 16384 cycles 32768 cycles 65536 cycles 131072 cycles 262144 cycles	262144 cycles	Number of cycles to wait for the main oscillator clock to stabilize.
