Bit 6—Compare Match Flag H (CMFH): Bit 6 is a status flag indicating a compare match

between TCFH and OCRFH. This flag is set by hardware and cleared by software. It cannot be set

by software.

Bit 6: CMFH

Description

[Clearing conditions]

(initial value)

After reading CMFH = 1, cleared by writing 0 to CMFH

[Setting conditions]

Set when the TCFH value matches OCRFH value

Bit 5—Timer Overflow Interrupt Enable H (OVIEH): Bit 5 enables or disables TCFH

overflow interrupts.

Bit 5: OVIEH

Description

TCFH overflow interrupt disabled

(initial value)

TCFH overflow interrupt enabled

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

Description

16-bit mode: TCF clearing by compare match disabled

(initial value)

8-bit mode: TCFH clearing by compare match disabled

16-bit mode: TCF clearing by compare match enabled

8-bit mode: TCFH clearing by compare match enabled

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

Description

[Clearing conditions]

(initial value)

After reading OVFL = 1, cleared by writing 0 to OVFL

[Setting conditions]

Set when the value of TCFL goes from H'FF to H'00
