NDERA is an eight-bit read/write register that enables TPC output groups 1 and 0 (TP7–TP0) on a
bit-by-bit basis.
When the bits enabled for TPC output by NDERA generate the ITU compare match selected in the
TPC output control register, the value of the next data register A (NDRA) is automatically
transferred to the corresponding PBDR bits and the output value is updated. For disabled bits,
there is no transfer and the output value does not change. NDERA is initialized to H'00 by a reset.
It is not initialized in standby mode.
Bits 7–0—Next Data Enable 7–0 (NDER7–NDER0): NDER7–NDER0 select enabling/disabling
for TPC output groups 1 and 0 (TP7–TP0) in bit units.

11.2.6
NDERB is an eight-bit read/write register that enables TPC output groups 3 and 2 (TP15–TP8) on
a bit-by-bit basis.
When the bits enabled for TPC output by NDERB generate the ITU compare match selected in the
TPC output control register, the value of the next data register B (NDRB) is automatically
transferred to the corresponding PBDR bits and the output value is updated. For disabled bits,
there is no transfer and the output value does not change. NDERB is initialized to H'00 by a reset.
It is not initialized in standby mode.
