The set values in the DRR1 register are valid for pins used as output.
The DRR10 bit is used to select 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 is used to select 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 DRR12 bit is used to select whether the drive capacity of the P5_0 to P5_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 DRR13 bit is used to select whether the drive capacity of the P5_4, P5_6, P5_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.
The DRR14 bit is used to select whether the drive capacity of the P6_0 to 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 is used to select whether the drive capacity of the P6_4 to 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.
