11.3.3 Next Data Registers H, L (NDRH, NDRL)
NDRH, NDRL store the next data for 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 2 and 3 have the same output trigger, all eight bits are mapped to the same
address and can be accessed at one time, as shown below.

Next Data Register 15 to 8
The register contents are transferred to the
corresponding PODRH bits by the output trigger
specified with PCR.
If pulse output groups 2 and 3 have different output triggers, upper 4 bits and lower 4 bits are
mapped to the different addresses as shown below.
