Output Offset Bits 1 - 0. These two bits define how soon the serial interface transmitter
output the bit 0 from the STo pin. The output stream offset can be selected to -45ns from
the point where the external frame pulse input signal is applied to the F0i inputs of the
device. See Table 11 and Figure 5
