Port 7 Data Register (P7DR)
P7DR is a 6-bit readable/writable register that stores output data for the port 7 pins (P7
Bits 7 and 6 are reserved; they return an undefined value if read, and cannot be modified.
P7DR is initialized to H'00 (bits 5 to 0) by a reset, and in hardware standby mode. It retains its
prior state in software standby mode.
Port 7 Register (PORT7)
Note: * Determined by state of pins P7
PORT7 is a 6-bit read-only register that shows the pin states. It cannot be written to. Writing of
output data for the port 7 pins (P7
Bits 7 and 6 are reserved, they return an undefined value if read, and cannot be modified.
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.
After a reset and in hardware standby mode, PORT7 contents are determined by the pin states, as
P7DDR and P7DR are initialized. PORT7 retains its prior state in software standby mode.
