Normal Framing
Frame groups A&B (FGx[0:11]) are programmed as output framing pulses for use with the local
serial data streams (see Figure 16 - “Frame Pulse Timing for Mode 2”). The position of the first
framing signal in a group is determined by an 11 bit quantity. The quantity is the FMIC state
number minus one. The quantity determines when the first framing signal in a group is to be
asserted high.
Inverted Framing
Identical to Normal Framing except the polarity of the framing pulses is logically inverted.
