For pins used as output, the setting values in the DRR1 register are valid.
The DRR10 bit selects whether the drive capacity of the P4_3 output transistor is set to low or high. This bit is
used to select whether the drive capacity of the output transistor is set to low or high for one pin.
The DRR11 bit selects whether the drive capacity of the P4_4 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.
The DRR14 bit selects whether the drive capacity of the P6_0 and P6_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 four pins.
The DRR15 bit selects whether the drive capacity of the P6_4 and P6_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.
