Internal Reset Detection Flag Register
IRSTSR
(0019H)
detection flag register (IRSCR). IRSCR<SYSRSF> corresponds to system clock reset, IRSCR<ADTRF> to address
trap reset, IRSCR<WDTF> to watchdog timer reset, and IRSCR<CLKSF> to clock stop detection reset. Each of these
bits is set to “1” when the corresponding reset is generated.
(external reset) to “L” level
Internal Reset Detection Flags
After an internal reset is released, the cause of this internal reset can be identified by reading the internal reset
To clear IRSCR<SYSRSF, ADTRF, WDTF, CLKSF> to “0”, write “1” in IRSCR<FCLR> or set the RESET pin
