Section 11 16-Bit Free-Running Timer
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 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 2—Output Compare Flag B (OCFB): This status flag indicates that the FRC value matches
the OCRB value. This flag must be cleared by software. It is set by hardware, however, and cannot
be set by software.
