LPOEN controls the LOOP[7:0] pins. Setting LPOEN to “1” configures LOOP[7:0] as outputs. The output value driven
on the pins are determined by the values written to LPO[7:0]. Setting LPOEN to “0” High-Z all the pins. In this mode,
the input values driven to these LOOP[7:0] can be read via LPI[7:0].
HIZ_B controls the RPOSx, RNEGx, and RCLKx pins. When HIZ_B is High, the outputs are enabled; when HIZ_B is
Low, the outputs are placed in a high impedance state (High-Z).
RDYOEN controls the ACK_B pin. Setting RDYOEN to “1” enables output on ACK_B. Setting ACKEN to “0” High -
Z the ACK_B pin.
