Bit 4—Counter Clear H (CCLRH): In 16-bit mode, bit 4 selects whether or not TCF is cleared
when a compare match occurs between TCF and OCRF.
In 8-bit mode, bit 4 selects whether or not TCFH is cleared when a compare match occurs between
TCFH and OCRFH.
Bit 4: CCLRH

Bit 3—Timer Overflow Flag L (OVFL): Bit 3 is a status flag indicating TCFL overflow (H'FF
to H'00). This flag is set by hardware and cleared by software. It cannot be set by software.
Bit 3: OVFL
0
1
Bit 2—Compare Match Flag L (CMFL): Bit 2 is a status flag indicating a compare match
between TCFL and OCRFL. This flag is set by hardware and cleared by software. It cannot be set
by software.
