9.2.2 Port 3 Data Register (P3DR)
P3DR stores output data for the port 3 pins (P36 to P30).
Bit Bit Name Initial Value R/W Description
7 — Undefined — Reserved
This bit is undefined and cannot be modified.
6 P36DR 0 R/W
5 P35DR 0 R/W
4 P34DR 0 R/W
3 P33DR 0 R/W
2 P32DR 0 R/W
1 P31DR 0 R/W
An output data for a pin is stored when the pin function is
specified to a general purpose output port.
0 P30DR 0 R/W

If a port 3 read is performed while P3DDR bits are set to
1, the P3DR values are read. If a port 3 read is performed
while P3DDR bits are cleared to 0, the pin states are read.
