Section 12 Programmable Pulse Generator (PPG)
12.3.3
NDRH and NDRL are 8-bit readable/writable registers that store the data for the next pulse output.
The NDR addresses differ depending on whether pulse output groups have the same output trigger
or different output triggers.

NDRH
If pulse output groups 3 and 2 have the same output trigger, all eight bits are mapped to the
same address and can be accessed at one time, as shown below.
If pulse output groups 3 and output pulse groups 2 have different output triggers, the upper 4
bits and the lower 4 bits are mapped to different addresses, as shown below.
