11.2.1
NDERH and NDERL are 8-bit readable/writable registers that enable or disable pulse output on a
bit-by-bit basis.
If a bit is enabled for pulse output by NDERH or NDERL, the NDR value is automatically
transferred to the corresponding PODR bit when the TPU compare match event specified by PCR
occurs, updating the output value. If pulse output is disabled, the bit value is not transferred from
NDR to PODR and the output value does not change.
NDERH and NDERL are each initialized to H'00 by a reset and in hardware standby mode. They
are not initialized in software standby mode.
