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 only accessible after the part is reset and before any registers are accessed using the serial control interface.
The state of each pin is set by tying it to 3.3 V (Logic 1) or 0 V (Logic 0).
