Input Offset Bits 2,1 & 0. These three bits define how long the serial interface receiver
takes to recognize and store bit 0 from the STio pin: i.e., to start a new frame. The input
frame offset can be selected to +4 clock periods from the point where the external frame
pulse input signal is applied to the F0i inputs of the device.
Data Latch Edge.
