P1DIR
P3
P3DIR
P3ALT
P1ALT
P1 and P1DIR is mapped on the same address and depend on the RMAP (SYSCON0.4)
bit to select between the two registers. By default (bit = 0), P1 occupies the address. If
the bit is set to 1 then P1DIR occupy the address.
P3 and P3DIR is mapped on the same address and depend on the RMAP (SYSCON0.4)
bit to select between the two registers. By default (bit = 0), P3 occupies the address. If
the bit is set to 1 then P3DIR occupy the address.
Ports 1 and 3 also serves alternate functions as listed in the
between the alternate function and normal I/O, registers P1ALT and P3ALT are used.
Each can be set to ’1’ for alternate functions, or reset to ’0’ for normal I/O.
