• Manufacturer: HITACHI [Hitachi Semiconductor]

To ensure input capture, the pulse width of the input capture signal should be at least 1.5 system
clock periods (1.5·ø).
The ICR is initialized to H'0000 at a reset and in the standby modes.
Note: When input capture is detected, the FRC value is transferred to the ICR even if the input
10.2.4 Timer Control Register (TCR)
Bit
Initial value
Read/Write
The TCR is an 8-bit readable/writable register that selects the FRC clock source, enables the
output compare signals, and enables interrupts.
The TCR is initialized to H'00 at a reset and in the standby modes.
Bit 7—Input Capture Interrupt Enable (ICIE): This bit selects whether to request an input
capture interrupt (ICI) when the input capture flag (ICF) in the timer status/control register
(TCSR) is set to “1.”

Bit 6—Output Compare Interrupt Enable B (OCIEB): This bit selects whether to request
output compare interrupt B (OCIB) when output compare flag B (OCFB) in the timer
status/control register (TCSR) is set to “1.”
