Section 9 I/O Ports
Port 6 Data Register (P6DR)
P6DR is an 8-bit readable/writable register that stores output data for pins P6₆ to P6₀. When this
register is read, the pin logic level is read for a bit with the corresponding P6DDR bit cleared to 0,
and the P6DR value is read for a bit with the corresponding P6DDR bit set to 1.

Port 6 data 6 to 0
These bits store data for port 6 pins
Bit 7 is reserved, cannot be modified, and always read as 1.
P6DR is initialized to H'80 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
