Section 12 Programmable Pulse Generator (PPG)
•
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.
Note: * When pulse output groups 2 and 3 have the same output trigger by PCR settings, the

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.
