Next Data Enable Register B (NDERB)

NDERB is an 8-bit readable/writable register that enables or disables TPC output groups 3 and 2
(TP
to TP
) on a bit-by-bit basis.

If a bit is enabled for TPC output by NDERB, then when the ITU compare match event selected in
the TPC output control register (TPCR) occurs, the NDRB value is automatically transferred to the
corresponding PBDR bit, updating the output value. If TPC output is disabled, the bit value is not
transferred from NDRB to PBDR and the output value does not change.
NDERB is initialized to H'00 by a reset and in hardware standby mode. It is not initialized in
software standby mode.
