The VLT0 register selects the voltage level of the input threshold values for ports P1, P3_3 to P3_5, and P3_7.
Bits VLT02 to VLT03 and bits VLT06 to VLT07 are used to select the input threshold values among three
voltage levels (0.35 VCC, 0.50 VCC, and 0.70 VCC).
The VLT1 register selects the voltage level of the input threshold values for ports P4_2 and P4_5 to P4_7. Bits
VLT10 to VLT15 are used to select the input threshold values among three voltage levels (0.35 VCC, 0.50
VCC, and 0.70 VCC).
