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 external clock periods (or 4.50 internal clock
cycles) 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 2.048 Mbps, the input offset cannot be adjusted
and the input offset bits have to be set to zero.
