Bit 4: Input Capture Flag D (ICFD)
This is a status flag indicating the fact that the value of the FRC has been transferred to the
ICRD by the input capture signals.
When an input capture signal occurs while the BUFEB of the TCRX is being set to 1, although
the ICFD will be set out, data transference to the ICRD will not be performed.
Therefore, in buffer operation, the ICFD can be used as an external interrupt by setting the
ICIDE bit to 1.
This flag should be cleared by use of the software. Such setting should only be made by use of
the hardware. It is not possible to make this setting using a software.
Bit 4
ICFD Description
0 [Clearing conditions]
When 0 is written into the ICFD after reading the ICFD under the setting of ICFD = 1
1 [Setting conditions]
When the input capture signal has occurred
Bit 3: Output Comparing Flag A (OCFA)
This is a status flag indicating the fact that the FRC and the OCRA have come to a comparing
match.
This flag should be cleared by use of the software. Such setting should only be made by use of
the hardware. It is not possible to make this setting using a software.
Bit 3
OCFA Description
0 [Clearing conditions]
When 0 is written into the OCFA after reading the OCFA under the setting of OCFA
= 1
1 [Setting conditions]
When the FRC and the OCRA have come to the comparing match
