RSTCSR controls the generation of the internal reset signal when TCNT overflows, and selects
the type of internal reset signal. RSTCSR is initialized to H'1F by a reset signal from the RES pin,
and not by the WDT internal reset signal caused by overflows.
Note: * Only 0 can be written, to clear the flag.

Description
This bit is set when TCNT overflows in watchdog timer
mode. This bit cannot be set in interval timer mode, and
only 0 can be written, to clear the flag.
[Setting condition]
Set when TCNT overflows (changed from H'FF to H'00) in
watchdog timer mode
[Clearing condition]
Cleared by reading RSTCSR when WOVF = 1, and then
writing 0 to WOVF
Reset Enable
Specifies whether or not a reset signal is generated in the
chip if TCNT overflows during watchdog timer operation.
0: Reset signal is not generated even if TCNT overflows
1: Reset signal is generated if TCNT overflows
Reserved
This bit can be read from and written to. However, the
write value should always be 0.
Reserved
These bits are always read as 1 and cannot be modified.
(Though this LSI is not reset, TCNT and TCSR in WDT
are reset)
