Port 6 Data Direction Register (P6DDR)
P6DDR is an 8-bit register that controls the input/output direction of each pin in port 6. A pin
functions as an output pin if the corresponding P6DDR bit is set to 1, and as an input pin if this bit
is cleared to 0.
P6DDR is a write-only register. Read data is invalid. If read, all bits always read 1.
P6DDR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode
it retains its existing values, so if a transition to software standby mode occurs while a P6DDR bit
is set to 1, the corresponding pin remains in the output state.
If a transition to software standby mode occurs while port 6 is being used by the free-running
timer, the timer will be initialized, so the pin will revert to general-purpose input/output,
controlled by P6DDR and P6DR.
Port 6 Data Register (P6DR)
P6DR is an 8-bit register that stores data for pins P6
6 is read, the value in P6DR is obtained directly, regardless of the actual pin state. When a P6DDR
bit is cleared to 0, if port 6 is read the pin state is obtained. This also applies to pins used as FRT
pins.
P6DR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its existing values.
