Notes: 1. Lower 16 bits of the address.
2. A bit that has been set for pulse output by NDER is read-only.
3. When the same output trigger is selected for pulse output groups 2 and 3 by the PCR
setting, the NDRH address is H'FE2C. When the output triggers are different, the
NDRH address is H'FE2E for group 2 and H'FE2C for group 3.
Similarly, when the same output trigger is selected for pulse output groups 0 and 1 by
the PCR setting, the NDRL address is H'FE2D. When the output triggers are different,
the NDRL address is H'FE2F for group 0 and H'FE2D for group 1.
4. The H8S/2633 Series has no pins corresponding to pulse output groups 0 and 1.
