Input Offset Bits 3,2,1 & 0. These four bits define how long the serial interface receiver
takes to recognize and store bit 0 from the STi pin: i.e., to start a new frame. The input
frame offset can be selected to +2.25 clock periods from the point where the external
frame pulse input signal is applied to the F0i inputs of the device. See Table 9.
When the STi pin has a stream rate of 2.048Mb/s, the input offset can not be adjusted
and the input offset bits have to be set to zero.
