For Atmel AT91M43300 — Special Functions

Simulation support for this peripheral or feature is comprised of:

  • Dialog boxes which display and allow you to change peripheral configuration.

These simulation capabilities are described below.

Special Function Registers Dialog

Special Function Registers

The Special Function Registers Dialog displays chip identification and other information specific to the ARM chip.

Chip ID Group

  • SF_CIDR (Chip ID Register) contains the chip ID number.
  • EXT (Extension Flag) set if an extended chip ID exists.
  • NVPTYP (Non Volatile Program Memory Type) displays the NV program memory series.
  • ARCH (Chip Architecture) displays the chip architecture.
  • VDSIZ (Volatile Data Memory Size) displays the amount of volatile data memory supported.
  • NVDSIZ (Non Volatile Data Memory Size) displays the amount of non-volatile data memory supported.
  • NVPSIZ (Non Volatile Program Memory Size) displays the amount of non-volatile data program supported.
  • VERSION (Version of the chip) displays the chip version.

Chip Extension Group

  • SF_EXID (Chip ID Extension Register) is reserved for future use.

Reset Status Group

  • SF_RSR (Reset Status Register) indicates a reset request from either an external source (NRST) or the Watchdog timer.

Protect Mode Group

  • SF_PMR (Protect Mode Register) contains the Protect Mode Resister Key (PMRKEY) and the Advanced Interrupt Controller Protect Mode values.
  • AIC (AIC Protect Mode Enable) is set to run the Advanced Interrupt Controller in Protect mode. If reset, the AIC runs in Normal mode.
