Watchdog Operation with 8-bit access
23.7.11 Watchdog Reset Count Register (WDOG_RSTCNT)
Address: WDOG_RSTCNT is 4005_2000h base + 14h offset = 4005_2014h
23.7.12 Watchdog Prescaler Register (WDOG_PRESC)
Address: WDOG_PRESC is 4005_2000h base + 16h offset = 4005_2016h

Counts the number of times the watchdog resets the system. This register is reset only on a POR. Writing
1 to the bit to be cleared, enables you to clear the contents of this register.
This read-only field is reserved and always has the value zero.
3-bit prescaler for the watchdog clock source. A value of zero indicates no division of the input WDOG
clock. The watchdog clock is divided by (PRESCVAL + 1) to provide the prescaled WDOG_CLK.
This read-only field is reserved and always has the value zero.
