Reset output enable
0 Reset signal is not output externally
1 Reset signal is output externally
Watchdog timer reset
0 [Clearing condition]
Reset signal input at RES pin.
Reading WRST when WRST=1, then writing 0 in WRST.
1 [Setting condition]
TCNT overflow generates a reset signal
Note: * Only 0 can be written in bit 7, to clear the flag.
