Bit 4
Input Capture Signal Edge Selection D (IEDGD): This bit works to select the rising
edge or falling edge of the input capture signal D (FTID).
Bit 4
IEDGD
Description
0
Captures the falling edge of the input capture signal D
(Initial value)
1
Captures the rising edge of the input capture signal D
Bit 3
Buffer Enabling A (BUFEA): This bit works to select whether or not to use the ICRC as
the buffer register for the ICRA.
Bit 3
BUFEA
Description
0
Not using the ICRC as the buffer register for the ICRA
(Initial value)
1
Using the ICRC as the buffer register for the ICRA
Bit 2
Buffer Enabling B (BUFEB): This bit works to select whether or not to use the ICRD as
the buffer register for the ICRB.
Bit 2
BUFEB
Description
0
Not using the ICRD as the buffer register for the ICRB
(Initial value)
1
Using the ICRD as the buffer register for the ICRB
Bits 1 and 0
Clock Select (CKS1, 0): These bits work to select the inputting clock to the FRC
from among three types of internal clocks and the DVCFG.
The DVCFG is the edge detecting pulse selected by the CFG dividing timer.
