CFI Framing Signal Output Control CMD2:FC2 … 0
This feature applies only if the configurable interface is clocked and synchronized via the
PCM interface clock and framing signals (PDC, PFS), i.e. if CMD1:CSS = 0.
In this case the EPIC delivers an output framing signal at pin FSC with a programmable
pulse width and position.
Note that the up- and downstream CFI frame position relative to the FSC output is not
affected by the setting of the CTAR and CBSR:CDS2 … 0 register bits.
Table 17 summarizes the 7 possible FSC Control (FC) modes:
