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

11.2.2
Note: * A bit that has been set for pulse output by NDER is read-only.
PODRH and PODRL are 8-bit readable/writable registers that store output data for use in pulse
output. However, the H8S/2646 Group has no pins corresponding to PODRL.
11.2.3
NDRH and NDRL are 8-bit readable/writable registers that store the next data for pulse output.
During pulse output, the contents of NDRH and NDRL are transferred to the corresponding bits in
PODRH and PODRL when the TPU compare match event specified by PCR occurs. The NDRH
and NDRL addresses differ depending on whether pulse output groups have the same output
trigger or different output triggers. For details see section 11.2.4, Notes on NDR Access.
NDRH and NDRL are each initialized to H'00 by a reset and in hardware standby mode. They are
not initialized in software standby mode.
11.2.4
The NDRH and NDRL addresses differ depending on whether pulse output groups have the same
output trigger or different output triggers.
