Offset Bits 2,1 & 0. These three bits define how long the serial interface receiver takes
to recognize and store bit 0 from the STi input 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 input of the device. See Figure 4.
