PARALLEL INTERFACE CONFIGURATION REGISTERS
The parallel interface configuration registers can be directly set using the PP_EN, PP_CH[1:0], PP_EQ, PP_PRE[1:0], PP_OTO, and
PP_OCL pins. This interface is accessible only after the part is reset and before any registers are accessed using the serial control interface.
Because most systems use serial control for the input termination resistors, the parallel control interface is limited to controlling the
AD8197B status after reset and before serial logic control. The state of each pin is set by tying it to 3.3 V (Logic 1) or 0 V (Logic 0).
