Section 9 I/O Ports
Port 6 Data Register (P6DR)
P6DR is an 8-bit readable/writable register that stores output data for the port 6 pins (P6
P6DR is initialized to H'00 by a power-on reset, and in hardware standby mode. It retains its prior
state after a manual reset, and in software standby mode.
Port 6 Register (PORT6)
PORT6 is an 8-bit read-only register that shows the pin states. It cannot be written to. Writing of
output data for the port 6 pins (P6
If a port 6 read is performed while P6DDR bits are set to 1, the P6DR values are read. If a port 6
read is performed while P6DDR bits are cleared to 0, the pin states are read.
After a power-on reset and in hardware standby mode, PORT6 contents are determined by the pin
states, as P6DDR and P6DR are initialized. PORT6 retains its prior state after a manual reset, and
in software standby mode.
