If pulse output groups 0 and 1 have the same output trigger, all eight bits are mapped to the
same address and can be accessed at one time, as shown below.

NDRH address is H¢FF4C. When they have different output triggers, the NDRH
addresses corresponding to the groups 2 and 3 are NDRHH (H¢FF4E) and NDRHL
(H¢FF4C), respectively. Also, when pulse output groups 0 and 1 have the same output
trigger by PCR settings, the NDRL address is NDRLH (H¢FF4D). When they have
different output triggers, the NDRL addresses corresponding to the groups 0 and 1 are
NDRLL (H¢FF4F) and H¢FF4D, respectively.
