Bit 1—Timer Overflow Flag (OVF): Status flag that indicates when FRC overflows (from H'FFFF
to H'0000). This flag is cleared by software and set by hardware. It cannot be set by software.
Bit 1: OVF
Description
0
[Clearing condition]
When OVF is read while set to 1, and then 0 is written to it
(Initial value)
1
[Setting condition]
When the FRC value changes from H'FFFF to H'0000
Bit 0—Counter Clear A (CCLRA): Selects whether or not to clear FRC on compare match A
(signal indicating match of FRC and OCRA).
Bit 0: CCLRA
Description
0
FRC clear disabled
(Initial value)
1
FRC cleared on compare match A

TCR is an 8-bit read/write register that selects the input edge for input capture and selects the
input clock for FRC. TCR is initialized to H'00 by a reset, in standby mode, and when the module
standby function is used.
Bit 7—Input Edge Select (IEDG): Selects whether to capture the input capture input (FTI) on the
falling edge or rising edge.
Bit 7: IEDG
Description
0
Input captured on falling edge
(Initial value)
1
Input captured on rising edge
Bits 6 to 2—Reserved: These bits are always read as 0. The write value should always be 0.
