Bit 6⎯Timer Mode Select (WT/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 software standby bit (SSBY) to 0 in SYSCR before setting TME. When setting SSBY to 1,
TME should be cleared to 0.
Bits 4 and 3⎯Reserved: These bits cannot be modified and are 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 (φ), for input to TCNT.
