Bit 6—Timer Mode Select (WT/IT IT IT IT): Selects whether to use the WDT as a watchdog timer or
interval timer. If used as an interval timer, the WDT generates an interval timer interrupt request
when TCNT overflows. If used as a watchdog timer, the WDT generates a reset signal when
TCNT overflows.
Bit 5—Timer Enable (TME): Selects whether TCNT runs or is halted.
When WT/IT = 1, clear the SYSCR software standby bit (SSBY) to 0, then set the TME to 1.
When SSBY is set to 1, clear TME to 0.
Bits 4 and 3—Reserved: Read-only bits, always read as 1.
Bits 2 to 0—Clock Select 2 to 0 (CKS2 to CKS0): These bits select one of eight internal clock
sources, obtained by prescaling the system clock ( ), for input to TCNT.
