Section 11 Programmable Pulse Generator (PPG)
11.3.1
NDERH and NDERL are 8-bit readable/writable registers that enable or disable pulse output on a
bit-by-bit basis. The corresponding DDR also needs to be set to 1 in order to enable pulse output
by the PPG.

Description
Next Data Enable 8 to 15
When a bit is set to 1 for pulse output by NDRH, the
value in the corresponding NDRH bit is transferred to
the PODRH bit by the selected output trigger. Values
are not transferred from NDRH to PODRH for cleared
bits.
Description
Next Data Enable 0 to 7
When a bit is set to 1 for pulse output by NDRL, the
value in the corresponding NDRL bit is transferred to
the PODRL bit by the selected output trigger. Values
are not transferred from NDRL to PODRL for cleared
bits.
