Port P11 Drive Capacity Control Register (P11DRR)

Note:

1. Both high-level output and low-level output are set to high drive capacity.

The P11DRR register selects whether the drive capacity of the P11 output transistor is set to low or high. The

P11DRRi 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.

7.4.21

Input Threshold Control Register 0 (VLT0)

The VLT0 register selects the voltage level of the input threshold values for ports P0 to P3. Bits VLT00 to

VLT07 are used to select the input threshold values among three voltage levels (0.35 VCC, 0.50 VCC, and 0.70

VCC).
