Reset Enable
Specifies whether or not a reset signal is generated
in the chip if TCNT overflows in watchdog timer
mode.
0: Reset signal is not generated even if TCNT
1: Reset signal is generated if TCNT overflows
Reset Select
Selects the type of internal reset generated if TCNT
overflows in watchdog timer mode.
0: Power-on reset
1: Manual reset
Reserved
These bits are always read as 1, and should only be
written with 1.
