Bit 7—Overflow Flag (OVF): Indicates that the watchdog timer count has overflowed from H'FF
to H'00.
Bit 7: OVF
0
1
Bit 6—Timer Mode Select (WT/IT): Selects whether to operate in watchdog timer mode or
interval timer mode. When TCNT overflows, an WOVF interrupt request is sent to the CPU in
interval timer mode. For watchdog timer mode, a reset or NMI interrupt is requested.
Bit 6: WT/IT
0
1
Bit 5—Timer Enable (TME): Enables or disables the timer.
Bit 5: TME
0
1
Bit 4—Reserved: This bit cannot be modified and is always read as 1.
Bit 3: Reset or NMI Select (RST/NMI): Selects either an internal reset or internal NMI function
at watchdog timer overflow.
Bit 3: RST/NMI
0

226
Description
To clear OVF, the CPU must read OVF after it has been set to 1, then write a 0
in this bit
Set to 1 when TCNT changes from H'FF to H'00
Description
Interval timer mode (WOVF request)
Watchdog timer mode (reset or NMI request)
Description
TCNT is initialized to H'00 and stopped
TCNT runs and requests a reset or an interrupt when it overflows
Description
NMI function enabled
Reset function enabled
