WDT0 Watchdog Timer 0 0x40003000 0x00 0x0400 registers WDT0 1 CTRL Watchdog Timer Control Register. 0x00 0x7FFFF000 INT_PERIOD Watchdog Interrupt Period. The watchdog timer will assert an interrupt, if enabled, if the CPU does not write the watchdog reset sequence to the WDT_RST register before the watchdog timer has counted this time period since the last timer reset. 0 4 wdt2pow31 2**31 clock cycles. 0 wdt2pow30 2**30 clock cycles. 1 wdt2pow29 2**29 clock cycles. 2 wdt2pow28 2**28 clock cycles. 3 wdt2pow27 2^27 clock cycles. 4 wdt2pow26 2**26 clock cycles. 5 wdt2pow25 2**25 clock cycles. 6 wdt2pow24 2**24 clock cycles. 7 wdt2pow23 2**23 clock cycles. 8 wdt2pow22 2**22 clock cycles. 9 wdt2pow21 2**21 clock cycles. 10 wdt2pow20 2**20 clock cycles. 11 wdt2pow19 2**19 clock cycles. 12 wdt2pow18 2**18 clock cycles. 13 wdt2pow17 2**17 clock cycles. 14 wdt2pow16 2**16 clock cycles. 15 RST_PERIOD Watchdog Reset Period. The watchdog timer will assert a reset, if enabled, if the CPU does not write the watchdog reset sequence to the WDT_RST register before the watchdog timer has counted this time period since the last timer reset. 4 4 wdt2pow31 2**31 clock cycles. 0 wdt2pow30 2**30 clock cycles. 1 wdt2pow29 2**29 clock cycles. 2 wdt2pow28 2**28 clock cycles. 3 wdt2pow27 2^27 clock cycles. 4 wdt2pow26 2**26 clock cycles. 5 wdt2pow25 2**25 clock cycles. 6 wdt2pow24 2**24 clock cycles. 7 wdt2pow23 2**23 clock cycles. 8 wdt2pow22 2**22 clock cycles. 9 wdt2pow21 2**21 clock cycles. 10 wdt2pow20 2**20 clock cycles. 11 wdt2pow19 2**19 clock cycles. 12 wdt2pow18 2**18 clock cycles. 13 wdt2pow17 2**17 clock cycles. 14 wdt2pow16 2**16 clock cycles. 15 WDT_EN Watchdog Timer Enable. 8 1 dis Disable. 0 en Enable. 1 INT_FLAG Watchdog Timer Interrupt Flag. 9 1 oneToClear inactive No interrupt is pending. 0 pending An interrupt is pending. 1 INT_EN Watchdog Timer Interrupt Enable. 10 1 dis Disable. 0 en Enable. 1 RST_EN Watchdog Timer Reset Enable. 11 1 dis Disable. 0 en Enable. 1 RST_FLAG Watchdog Timer Reset Flag. 31 1 read-write noEvent The event has not occurred. 0 occurred The event has occurred. 1 RST Watchdog Timer Reset Register. 0x04 write-only WDT_RST Writing the watchdog counter 'reset sequence' to this register resets the watchdog counter. If the watchdog count exceeds INT_PERIOD then a watchdog interrupt will occur, if enabled. If the watchdog count exceeds RST_PERIOD then a watchdog reset will occur, if enabled. 0 8 seq0 The first value to be written to reset the WDT. 0x000000A5 seq1 The second value to be written to reset the WDT. 0x0000005A
