WDTCNT is a 32-bit read-only register comprising a 12-bit counter that is incremented by the
WDTBCNT overflow signal. When WDTCNT overflows, a reset of the selected type is initiated
in watchdog timer mode, or an interrupt is generated in interval timer mode.
WDTCNT is only reset by a power-on reset. Writing to this register is invalid.
