LVISEL[1:0] — LVI Operating Mode Selection
Setting PCEH configures the PTC4/FP23–PTC7/FP26 pins for LCD
frontplane driver use. Reset clears this bit.
Setting PCEL configures the PTC0/FP19–PTC3/FP22 pins for LCD
frontplane driver use. Reset clears this bit.
LVISEL[1:0] selects the voltage operating mode of the LVI module.
