Timing is described in section 11.3, Operation.
Bit 7—Input Capture Flag A (ICFA): This status flag indicates that the FRC value has been
transferred to ICRA by means of an input capture signal. When BUFEA = 1, ICFA indicates that
the old ICRA value has been moved into ICRC and the new FRC value has been transferred to
ICRA.
ICFA must be cleared by software. It is set by hardware, however, and cannot be set by software.
Bit 6—Input Capture Flag B (ICFB): This status flag indicates that the FRC value has been
transferred to ICRB by means of an input capture signal. When BUFEB = 1, ICFB indicates that
the old ICRB value has been moved into ICRD and the new FRC value has been transferred to
ICRB.
ICFB must be cleared by software. It is set by hardware, however, and cannot be set by software.
Bit 5—Input Capture Flag C (ICFC): This status flag indicates that the FRC value has been
transferred to ICRC by means of an input capture signal. When BUFEA = 1, on occurrence of the
signal transition in FTIC (input capture signal) specified by the IEDGC bit, ICFC is set but data is
not transferred to ICRC. Therefore, in buffer operation, ICFC can be used as an external interrupt
signal (by setting the ICICE bit to 1).
ICFC must be cleared by software. It is set by hardware, however, and cannot be set by software.
