• Bit 7 (watchdog timer overflow (WOVF)): WOVF indicates that the TCNT has overflowed
Bit 7: WOVF

• Bit 6 (reset enable (RSTE)): RSTE selects whether to reset the chip internally if the TCNT
Bit 6: RSTE

• Bit 5 (reset select (RSTS)): RSTS selects the type of internal reset generated if the TCNT
Bit 5: RSTS
0

Description
No TCNT overflow in watchdog timer mode (initial value)
Cleared when software reads WOVF, then writes 0 in WOVF
Set by TCNT overflow in watchdog timer mode
Description
Not reset when TCNT overflows (initial value). LSI not reset internally,
but TCNT and TCSR reset within WDT.
Reset when TCNT overflows
