Read/Write:
ICRGF is an 8-bit read-only register. When a falling edge of the input capture input signal is
detected, the current TCG value is transferred to ICRGF. If IIEGS in TMG is 1 at this time,
IRRTG in IRR2 is set to 1, and if IENTG in IENR2 is 1, an interrupt request is sent to the CPU.
For details of the interrupt, see section 3.3, Interrupts.
To ensure dependable input capture operation, the pulse width of the input capture input signal
must be at least 2φ or 2φ
SUB
(when the noise canceler is not used).
ICRGF is initialized to H'00 upon reset.

ICRGR is an 8-bit read-only register. When a rising edge of the input capture input signal is
detected, the current TCG value is transferred to ICRGR. If IIEGS in TMG is 0 at this time,
IRRTG in IRR2 is set to 1, and if IENTG in IENR2 is 1, an interrupt request is sent to the CPU.
