• Bit 8—Overflow Flag 1A (OVF1A): Status flag that indicates TCNT1A overflow.

Bit 8: OVF1A

Description

[Clearing condition]

(Initial value)

When OVF1A is read while set to 1, then 0 is written to OVF1A

[Setting condition]

When the TCNT1A value overflows (from H'FFFF to H'0000)

• Bit 7—Input Capture/Compare-Match Flag 1H (IMF1H): Status flag that indicates GR1H

input capture or compare-match.

Bit 7: IMF1H

Description

[Clearing condition]

(Initial value)

When IMF1H is read while set to 1, then 0 is written to IMF1H

[Setting conditions]

• When the TCNT1A value is transferred to GR1H by an input capture

signal while GR1H is functioning as an input capture register

•••• When TCNT1A = GR1H while GR1H is functioning as an output compare

• Bit 6—Input Capture/Compare-Match Flag 1G (IMF1G): Status flag that indicates GR1G

input capture or compare-match.

Bit 6: IMF1G

Description

[Clearing condition]

(Initial value)

When IMF1G is read while set to 1, then 0 is written to IMF1G

[Setting conditions]

•••• When the TCNT1A value is transferred to GR1G by an input capture

signal while GR1G is functioning as an input capture register

•••• When TCNT1A = GR1G while GR1G is functioning as an output compare
