11.2.2
Note: * Only 0 can be written, to clear the flag.
TCSR is an 8-bit readable/writable * register. Its functions include selecting the clock source to be
input to TCNT, and the timer mode.
TCR is initialized to H'18 by a reset and in hardware standby mode. It is not initialized in software
standby mode.
Note: * TCSR is write-protected by a password to prevent accidental overwriting. For details see
Bit 7—Overflow Flag (OVF): Indicates that TCNT has overflowed from H'FF to H'00, when in
interval timer mode. This flag cannot be set during watchdog timer operation.

Note: * When OVF is polled and the interval timer interrupt is disabled, OVF = 1 must be read at
Bit 6—Timer Mode Select (WT/IT): Selects whether the WDT is used as a watchdog timer or
interval timer. If used as an interval timer, the WDT generates an interval timer interrupt request
(WOVI) when TCNT overflows. If used as a watchdog timer, the WDT generates the WDTOVF
