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.

Reset Enable
Specifies whether or not this LSI is internally reset if
TCNT overflows during watchdog timer operation.
0: LSI is not reset even if TCNT overflows (Though this
1: LSI is reset if TCNT overflows
Reserved
Although this bit is readable/writable, reading from or
writing to this bit does not affect operation.
Reserved
These are read-only bits and cannot be modified.
LSI is not reset, TCNT and TCSR in WDT are reset)
