• Manufacturer Part Number: hd64338342hw
• Description: Renesas 8-bit Single-chip Microcomputer H8 Family/h8/300l Super Low Power Series
• Manufacturer: Renesas Electronics Corporation.

When TCG overflows from H'FF to H'00, if OVIE in TMG is 1, IRRTG is set to 1 in IRR2, 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.
TCG cannot be read or written by the CPU. It is initialized to H'00 upon reset.
Note: * An input capture signal may be generated when TMIG is modified.
2. Input Capture Register GF (ICRGF)
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 is set to 1 in IRR2, 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 2 or 2
ICRGF is initialized to H'00 upon reset.
3. Input Capture Register GR (ICRGR)
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 1 at this time,
IRRTG is set to 1 in IRR2, 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 2 or 2
