• Description: Hardware Manual
• Manufacturer: Hitachi Semiconductor

Bit 3—Output Compare Interrupt A Enable (OCIAE): Selects enabling/disabling of the OCIA
interrupt request when the output compare flag A (OCFA) in FTCSR is set to 1.
Bit 3: OCIAE
0
1
Bit 2—Output Compare Interrupt B Enable (OCIBE): Selects enabling/disabling of the OCIB
interrupt request when the output compare flag B (OCFB) in FTCSR is set to 1.
Bit 2: OCIBE
0
1
Bit 1—Timer Overflow Interrupt Enable (OVIE): Selects enabling/disabling of the OVI interrupt
request when the overflow flag (OVF) in FTCSR is set to 1.
Bit 1: OVIE
0
1
Bit 0—Reserved: This bit is always read as 1. The write value should always be 1.
12.2.5
Note: * For bits 7, and 3 to 1, the only value that can be written is 0 (to clear the flags).
FTCSR is an 8-bit register that selects counter clearing and controls interrupt request signals.
FTCSR is initialized to H'00 by a reset, in standby mode, and when the module standby function is
used. See section 12.4, Operation, for the timing.
Bit 7—Input Capture Flag (ICF): Status flag that indicates that the FRC value has been sent to
FICR by the input capture signal. This flag is cleared by software and set by hardware. It cannot
be set by software.
