For pins used as output, the setting values in the DRR0 register are valid.
The DRR06 bit selects whether the drive capacity of the P3_3 output transistors is set to low or high. This bit is
used to select whether the drive capacity of the output transistors is set to low or high for this pin.
The DRR07 bit selects whether the drive capacity of the P3_4, P3_5, P3_7 output transistors is set to low or
high. This bit is used to select whether the drive capacity of the output transistors is set to low or high for three
pins.
For pins used as output, the setting values in the DRR1 register are valid.
The DRR11 bit selects whether the drive capacity of the P4_5 to P4_7 output transistors is set to low or high.
This bit is used to select whether the drive capacity of the output transistors is set to low or high for four pins.
