• Manufacturer Part Number: h8s-2646
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2600 Series
• Manufacturer: Renesas Electronics Corporation.

Different Triggers for Pulse Output Groups: If pulse output groups 2 and 3 are triggered by
different compare match events, the address of the upper 4 bits in NDRH (group 3) is H'FE2C and
the address of the lower 4 bits (group 2) is H'FE2E. Bits 3 to 0 of address H'FE2C and bits 7 to 4
of address H'FE2E are reserved bits that cannot be modified and are always read as 1.
Address H'FE2C
Address H'FE2E
If pulse output groups 0 and 1 are triggered by different compare match event, the address of the
upper 4 bits in NDRL (group 1) is H'FE2D and the address of the lower 4 bits (group 0) is
H'FE2F. Bits 3 to 0 of address H'FE2D and bits 7 to 4 of address H'FE2F are reserved bits that
cannot be modified and are always read as 1. However, the H8S/2646 Group has no output pins
corresponding to pulse output groups 0 and 1.
