9.2.8 Next Data Enable Register B (NDERB)
NDERB is an 8-bit readable/writable register that enables or disables TPC output groups 3 and 2
(TP15 to TP8)* on a bit-by-bit basis.

These bits enable or disable
TPC output groups 3 and 2
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.
Bits 7 to 0—Next Data Enable 15 to 8 (NDER15 to NDER8): These bits enable or disable TPC
output groups 3 and 2 (TP15 to TP8)* on a bit-by-bit basis.

Note: * Since this LSI does not have a TP14 pin, the TP14 signal cannot be output to the outside.
