Description

CONFIG register

Fields

REMAP

CPU access routing (it supersedes PREMAP configuration):

  • 0 : FLASH memory addressed
  • 1 : SRAM0 memory addressed
DIS_GROUP_WRITE

Burst write Control:

  • 0 : burst write allowed
  • 1 : burst write forbidden
WAIT_STATE

Add latency to flash read opeations:

  • 00 : no latency
  • 01 : 1 clock cycle latency
  • 10 : 2 clock cycles latency
  • 11 : 3 clock cycles latency
SLEEP_SM

Flash memory power-down mode enable in SLEEP mode This bit allows to have the Flash memory in power-down mode or in idle mode when the device is in Sleep mode.

  • 0: When the device is in Sleep mode, the NVM is in Idle mode.
  • 1: When the device is in Sleep mode, the NVM is in power-down mode.
