As all of 8 bits of port C become
control pins in this case, D
3
and
D
0
bits are treated as "Don't Care".
No I/O specification is required for mode 2,
since it is a bidirectional operation.
This bit is therefore treated as "Don't Care".
When group A is set to mode 2, this bit is treated
as "Don't Care".
