Description
Watchdog Timer On
TCWD starts counting up when WDON is set to 1 and
halts when WDON is cleared to 0.
[Setting condition]
When 1 is written to the WDON bit while writing 0 to the
B2WI bit when the TCSRWE bit=1
[Clearing conditions]
Bit 0 Write Inhibit
This bit can be written to the WRST bit only when the
write value of the B0WI bit is 0. This bit is always read as
1.
Watchdog Timer Reset
[Setting condition]
When TCWD overflows and an internal reset signal is
generated
[Clearing conditions]
Reset by RES pin
When 0 is written to the WDON bit while writing 0 to
the B2WI when the TCSRWE bit = 1
Reset by RES pin
When 0 is written to the WRST bit while writing 0 to
the B0WI bit when the TCSRWE bit=1
