Port 3 Data Direction Register (P3DDR)
P3DDR is an 8-bit write-only register that can select input or output for each pin in port 3.
Modes 1 to 6 (Expanded Modes): Port 3 functions as a data bus. P3DDR is ignored.
Mode 7 (Single-Chip Mode): Port 3 functions as an input/output port. A pin in port 3 becomes an
output port if the corresponding P3DDR bit is set to 1, and an input port if this bit is cleared to 0.
P3DDR is a write-only register. Its value cannot be read. All bits return 1 when read.
P3DDR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode
it retains its previous setting. If a P3DDR bit is set to 1, the corresponding pin maintains its output
state in software standby mode.
Port 3 Data Register (P3DR)
P3DR is an 8-bit readable/writable register that stores output data for pins P3
acts as an output port, the value of this register is output. When a bit in P3DDR is set to 1, if port 3
is read the value of the corresponding P3DR bit is returned. When a bit in P3DDR is cleared to 0,
if port 3 is read the corresponding pin level is read.
P3DR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
