The following pages contain some working sheets to facilitate the programming of the
EPIC-1. For several tasks (i.e. initialization, time slot switching, ...) the corresponding
registers are summarized in a way the programmer gets a quick overview on the
registers he has to use.

If A4 is connected to ground, the registers are addressed by A3..A0 and RBS. This is
compatible to the EPIC-1.

CMC address field) is used in downstream direction for the D-channel handling of
SACCO_A with the arbiter.
PCM input and output data can be shifted additionally by one PDC clock (see register
bits PCSR:DRCS and PCSR:ADSRO). If these two bits are not set, the ELIC-EPIC is
compatible to the EPIC-1.
This feature guarantees the capability to adapt to a PCM data stream also in double
clock rate mode (unlike the EPIC-1 up to Version A3), when the negative PDC edge
is used to synchronize PFS.
PCM clock also in CFI mode 0. See register EMOD:ECMD2.
