Bits 12:8 – CALVREFH[4:0] Calibration Voltage Reference High Value
If the RDSRC field is set to 2, when the TCPC input calibration value is higher than CALVREFH, the Rd pull-down resistor is decreased by 10% from its default value.
Bits 4:0 – CALVREFL[4:0] Calibration Voltage Reference Low Value
If the RDSRC field is set to 2, when the TCPC input calibration value is lower than CALVREFL, the Rd pull-down resistor is increased by 10% from its default value.
