The P1DRR register selects whether the drive capacity of the P1 output transistor is set to low or high.
The P1DRRi bit (i = 0 to 7) is used to select whether the drive capacity of the output transistor is set to low or
high for each pin.
For pins used as output, the setting values in the P1DRR register are valid.
The P2DRR register selects whether the drive capacity of the P2 output transistor is set to low or high. The
P2DRRi bit (i = 0 to 7) is used to select whether the drive capacity of the output transistor is set to low or high
for each pin.
For pins used as output, the setting values in the P2DRR register are valid.
