Description
Overflow Flag
Indicates that TCNT has overflowed (changes from H'FF
to H'00).
[Setting condition]
When TCNT overflows (changes from H'FF to H'00)
However, when internal reset request generation is
selected in watchdog timer mode, OVF is cleared
automatically by the internal reset.
[Clearing conditions]
Timer Mode Select
Selects whether the WDT is used as a watchdog timer or
interval timer.
0: Interval timer mode
1: Watchdog timer mode
Timer Enable
When this bit is set to 1, TCNT starts counting.
When this bit is cleared, TCNT stops counting and is
initialized to H'00.
Prescaler Select
Selects the clock source to be input to TCNT.
0: Counts the divided cycle of –based prescaler (PSM)
1: Counts the divided cycle of SUB–based prescaler
Reset or NMI
Selects to request an internal reset or an NMI interrupt
when TCNT has overflowed.
0: An NMI interrupt is requested
1: An internal reset is requested
(PSS)
When TCSR is read when OVF = 1 *
written to OVF
When 0 is written to TME
