Input capture register GF (ICRGF)
ICRGF is an 8-bit read-only register. When the falling edge of the input capture signal is detected,
the TCG value at that time is transferred to ICRGF. If the input capture interrupt select bit (IIEGS)
is set to 1 in TMG, bit IRRTG in interrupt request register 2 (IRR2) is set to 1. If in addition bit
IENTG in interrupt enable register 2 (IENR2) is set to 1, a CPU interrupt is requested. Details on
interrupts are given in 3.3, Interrupts.
To ensure proper input capture when the noise canceller is not used, the pulse width of the input
capture signal should be at least 2 or 2
Upon reset, ICRGF is initialized to H'00.
Input Capture Register GR (ICRGR)
ICRGR is an 8-bit read-only register. When the rising edge of the input capture signal is detected,
the TCG value at that time is sent to ICRGR. If the IIEGS bit is cleared to 0 in TMG, bit IRRTG
in interrupt request register 2 (IRR2) is set to 1. If in addition bit IENTG in interrupt enable
register 2 (IENR2) is set to 1, a CPU interrupt is requested. Details on interrupts are given in 3.3,
Interrupts.
To ensure proper input capture when the noise canceller is not used, the pulse width of the input
capture signal should be at least 2 or 2
Upon reset, ICRGR is initialized to H'00.
