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.
