4. Timer control/status register F (TCSRF)
Note: * Bits 7, 6, 3, and 2 can only be written with 0, for flag clearing.
TCSRF is an 8-bit read/write register that performs counter clear selection, overflow flag setting,
and compare match flag setting, and controls enabling of overflow interrupt requests.
TCSRF is initialized to H'00 upon reset.
Bit 7: Timer overflow flag H (OVFH)
Bit 7 is a status flag indicating that TCFH has overflowed from H'FF to H'00. This flag is set by
hardware and cleared by software. It cannot be set by software.

Bit 6: Compare match flag H (CMFH)
Bit 6 is a status flag indicating that TCFH has matched OCRFH. This flag is set by hardware and
cleared by software. It cannot be set by software.
