Notes: *1 Lower 16 bits of the address.
*2 Bits used for pulse output cannot be written to.
*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/2646 Series has no pins corresponding to pulse output groups 0 and 1.
