Description
(Note 1)
OFn1, OFn0
(n = 0 to 31)
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 -45 ns
from the point where the external frame pulse input signal is applied to the F0i inputs of
the device. See Table 11 and Figure 6.
