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. When reset, NDERB is initialized to
H'00. It is not initialized by standby mode.
