Description

ICFB

R/(W)* Input Capture Flag B

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

ICFC

R/(W)* Input Capture Flag C

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

ICFD

R/(W)* Input Capture Flag D

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
