Bit 5

ICFC

Description

[Clearing condition]

Read ICFC when ICFC = 1, then write 0 in ICFC

(Initial value)

[Setting condition]

When an input capture signal is received

Bit 4—Input Capture Flag D (ICFD): This status flag indicates that the FRC value has been

transferred to ICRD by means of an input capture signal. When BUFEB = 1, on occurrence of the

signal transition in FTID (input capture signal) specified by the IEDGD bit, ICFD is set but data is

not transferred to ICRD. Therefore, in buffer operation, ICFD can be used as an external interrupt

by setting the ICIDE bit to 1.

ICFD must be cleared by software. It is set by hardware, however, and cannot be set by software.

Bit 4

ICFD

Description

[Clearing condition]

Read ICFD when ICFD = 1, then write 0 in ICFD

(Initial value)

[Setting condition]

When an input capture signal is received

Bit 3—Output Compare Flag A (OCFA): This status flag indicates that the FRC value matches

the OCRA value. This flag must be cleared by software. It is set by hardware, however, and

cannot be set by software.

Bit 3

OCFA

Description

[Clearing condition]

Read OCFA when OCFA = 1, then write 0 in OCFA

(Initial value)

[Setting condition]

When FRC = OCRA
