Description
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. Only 0 can be
written to this bit to clear the flag.
[Setting condition]
When an input capture signal causes the FRC value to
be transferred to ICRB
[Clearing condition]
Read ICFB when ICFB = 1, then write 0 to ICFB
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 an input
capture signal specified by the IEDGC bit at the FTIC
input pin, ICFC is set but data is not transferred to
ICRC. In buffer operation, ICFC can be used as an
external interrupt signal by setting the ICICE bit to 1.
Only 0 can be written to this bit to clear the flag.
[Setting condition]
When an input capture signal is received
[Clearing condition]
Read ICFC when ICFC = 1, then write 0 to ICFC
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 an input
capture signal specified by the IEDGD bit at the FTID
input pin, ICFD is set but data is not transferred to
ICRD. In buffer operation, ICFD can be used as an
external interrupt signal by setting the ICIDE bit to 1.
Only 0 can be written to this bit to clear the flag.
[Setting condition]
When an input capture signal is received
[Clearing condition]
Read ICFD when ICFD = 1, then write 0 to ICFD
