ELIC CFI-Mode Bit 2.
If set to ’0’, the CFI-mode 0 with a 2.048-MBit/s data rate can be used with a
2.048-MHz PDC-input clock.
This mode requires further restrictions of the current ELIC-specification:
1) EPIC-1 PMOD:PCR must be set to ’1’.
2) EPIC-1 CMD2:COC must be programmed to ’0’, i.e. it is not possible to
3) EPIC-1 CMD1:CSS must be programmed to ’0’, i.e. it is not possible to
4) The timing of the PCM-interface is expanded:

Note: Although the PCM clock PDC is set to double clock rate by this bit,
output a DCL-clock with a frequency of twice the CFI-data rate.
select DCL as clock and FSC as framing signal source for the
configurable interface.
