Detailed Description

Build Time Configurations for ra4m3_fsp

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

ConfigurationOptionsDefaultDescription
Security
Security > Exceptions
Exception Response
  • Non-Maskable Interrupt
  • Reset
Non-Maskable Interrupt Configure the result of a TrustZone Filter exception. This exception is generated when the TrustZone Filter detects access to a protected region.

This setting is only valid when building projects with TrustZone.
BusFault, HardFault, and NMI Target
  • Non-Secure State
  • Secure State
Secure State Value for SCB->AIRCR register bit BFHFNMINS. Defines whether BusFault and NMI exceptions are Non-secure, and whether exceptions target the Non-secure HardFault exception.

This setting is only valid when building projects with TrustZone.
Prioritize Secure Exceptions
  • Enabled
  • Disabled
Disabled Value for SCB->AIRCR register bit PRIS. When enabled, all Non-secure interrupt priorities are automatically demoted by right shifting their priority by one then setting the most significant bit. As there is effectively one less bit care must be taken to ensure the prioritization of non-secure interrupts is correct.

This setting is only valid when building projects with TrustZone.
Security > SRAM Accessibility
SRAM Protection
  • Both Secure and Non-Secure State
  • Secure State
Both Secure and Non-Secure State Defines whether SRAMPRCR is write accessible for the Non-secure application.

This setting is only valid when building projects with TrustZone.
SRAM ECC
  • Both Secure and Non-Secure State
  • Secure State
Both Secure and Non-Secure State Defines whether SRAM ECC registers are write accessible for the Non-secure application.

This setting is only valid when building projects with TrustZone.
Standby RAM
  • Regions 7-0 are all Secure.
  • Region 7 is Non-secure. Regions 6-0 are Secure.
  • Regions 7-6 are Non-secure. Regions 5-0 are Secure.
  • Regions 7-5 are Non-secure. Regions 4-0 are Secure.
  • Regions 7-4 are Non-secure. Regions 3-0 are Secure.
  • Regions 7-3 are Non-secure. Regions 2-0 are Secure.
  • Regions 7-2 are Non-secure. Regions 1-0 are Secure.
  • Regions 7-1 are Non-secure. Region 0 is Secure.
  • Regions 7-0 are all Non-secure.
config.bsp.fsp.tz.stbramsar.both Defines whether Standby RAM registers are accessible for the Non-secure application.

This setting is only valid when building projects with TrustZone.
Security > BUS Accessibility
Bus Security Attribution Register A
  • Both Secure and Non-Secure State
  • Secure State
Both Secure and Non-Secure State Defines whether the Slave Bus Control Registers (BUSSCNT<slave>) are write accessible for the Non-secure application.

This setting is only valid when building projects with TrustZone.
Bus Security Attribution Register B
  • Both Secure and Non-Secure State
  • Secure State
Both Secure and Non-Secure State Defines whether the Bus and DMAC/DTC Error Clear Registers are write accessible for the Non-secure application.

This setting is only valid when building projects with TrustZone.
System Reset Request Accessibility
  • Both Secure and Non-Secure State
  • Secure State
Secure State Value for SCB->AIRCR register bit SYSRESETREQS. Defines whether the SYSRESETREQ bit is functional for Non-secure use.

This setting is only valid when building projects with TrustZone.
Cache Accessibility
  • Both Secure and Non-Secure State
  • Secure State
Both Secure and Non-Secure State Defines whether the Cache registers are write accessible for the Non-secure application.

This setting is only valid when building protjects with TrustZone.
System Reset Status Accessibility
  • Both Secure and Non-Secure State
  • Secure State
Both Secure and Non-Secure State Defines whether the reset status registers (RSTSRn) can be cleared from the Non-secure application.

This setting is only valid when building projects with TrustZone.
Battery Backup Accessibility
  • Both Secure and Non-Secure State
  • Secure State
Both Secure and Non-Secure State Defines whether the battery backup registers are accessible for the Non-secure application. If Secure State is selected, all battery backup registers are read only except for VBTBKRn registers which are both read and write protected.

This setting is only valid when building projects with TrustZone.
Uninitialized Non-Secure Application Fallback
  • Enable Uninitialized Non-Secure Application Fallback
  • Disable Uninitialized Non-Secure Application Fallback
Enable Uninitialized Non-Secure Application Fallback If enabled, the secure application checks if the non-secure application has been programmed in non-secure flash before branching. If the non-secure application has not been programmed, then the secure application branches to an infinite loop in non-secure RAM. This prevents an issue where the debugger may not connect if the MCU is configured in the NSECSD lifecycle state.

Clocks
HOCO FLL Function
  • Enabled
  • Disabled
Disabled Setting this option to Enabled improves HOCO accuracy significantly by using the subclock, but incurs certain restrictions.

The FLL function requires the subclock oscillator to be running and stabilized. When enabled and running the PLL or system clock from HOCO, the BSP will wait for both the Subclock Stabilization Time as well as the FLL Stabilization Time when setting up clocks at startup.

When FLL is enabled Software Standby and Deep Software Standby modes are not available.
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.
Startup C-Cache Line Size

  • 64 Bytes
32 Bytes Set the C-Cache line size configured during startup.
