HVTOFF â Disable of Port C Inputs
This data bit controls the operation of the Port C Inputs
1 = Port C High Voltage Inputs (PC0 - PC4) disabled
0 = Port C High Voltage Inputs enabled
VSCAL â Disable of VSUP Scaler Circuit
This data bit controls the operation of the VSUP scaler circuit
1 = VSUP scaler disabled, this mode saves power consumption
0 = VSUP scaler enabled, VSUP can be measured using the A/D
converter channel 7
LSOFF â Low Side Drivers Off
This data bit controls the operation of PC5-6 and the temperature
sensor block
1 = PC5-6 and temperature block disabled to minimize power
consumption
0 = PC5-6 and and temperature block enabled
