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.
Bit Bit Name
7 NDR15
6 NDR14
5 NDR13
4 NDR12
3 NDR11
2 NDR10
1 NDR9
0 NDR8
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.
