• Manufacturer Part Number: h8s-2649
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2600 Series
• Manufacturer: Renesas Electronics Corporation.

When a rising edge is input to the TIOCA1 and TIOCA2 pins simultaneously, the upper 16 bits of
the 32-bit data are transferred to TGRA_1, and the lower 16 bits to TGRA_2.
Figure 10.19 illustrates the operation when TCNT_2 overflow/underflow counting has been set for
TCNT_1 and phase counting mode has been designated for channel 2.
TCNT_1 is incremented by TCNT_2 overflow and decremented by TCNT_2 underflow.
