10.7.2 Port 7 Data Register (P7DR)
P7DR stores output data for the port 7 pins.
Bit Bit Name Initial Value R/W Description
7, 6 — All 0 — Reserved
These bits are always read as 0 and cannot be
modified.
5 P75DR 0 R/W
4 P74DR 0 R/W
3 P73DR 0 R/W
2 P72DR 0 R/W
1 P71DR 0 R/W
0 P70DR 0 R/W
Output data for a pin is stored when the pin function
is specified to a general purpose I/O.
10.7.3 Port 7 Register (PORT7)
PORT7 shows the pin states.
PORT7 cannot be modified.
Bit Bit Name Initial Value R/W Description
7, 6 — Undefined — Reserved
These bits are reserved, if read they will return an
undefined value.

If a port 7 read is performed while P7DDR bits are
set to 1, the P7DR values are read. If a port 7 read
is performed while P7DDR bits are cleared to 0, the
pin states are read.
Note: * Determined by the states of pins P75 to P70.
