DESCRIPTION
A-side supply voltage (0.8 V to 3.6 V)
Serial clock bus, A-side. Connect to V_CCA through a pull-up resistor, even if unused
Serial data bus, A-side. Connect to V_CCA through a pull-up resistor, even if unused
Ground
Active-high repeater enable input, referenced to V_CCA
Serial data bus, B-side. Do NOT connect to V_CCB through a pull-up resistor for proper operation. If
unused, leave floating
