Notes: 1. Lower 16 bits of the address.

2. Bits used for TPC output cannot be written.

3. The NDRA address is H'FFA5 when the same output trigger is selected for TPC output

groups 0 and 1 by settings in TPCR. When the output triggers are different, the NDRA

address is H'FFA7 for group 0 and H'FFA5 for group 1. Similarly, the address of NDRB

is H'FFA4 when the same output trigger is selected for TPC output groups 2 and 3 by

settings in TPCR. When the output triggers are different, the NDRB address is H'FFA6

for group 2 and H'FFA4 for group 3.
