5) PCSR:DRE has to be set to ‘1’.
6) PMOD:PSM has to be set to ’1’.
Demultiplexed Address.
If set to '0' the demultiplexed addresses are also valid in the multiplexed
P-interface mode.
PCSR:URE has to be set to ‘1’.
When provided with a 2 MHz PDC, the ELIC internally generates a
4 MHz clock.
Since the clock shift capabilities (provided by register bits PCSR:DRCS
and PCSR:ADSR0) apply to the internal 4 MHz clock, the frame can thus
be shifted with a resolution of a half bit.

Timing Relation Between Internal and External Clock
The frame signal PFS must always be sampled with the rising edge of
PDC. The set-up and hold times of PFS are still valid respected to
external PDC.
