Overview

1.6 Using the EPIC-S

The EPIC-S is based on the same technology as the EPIC-1 aside from only providing

CFI port 0 and CFI port 1. Therefore this User’s Manual applies to both, the EPIC-S and

the EPIC-1.

When using the EPIC-S the user has to be aware not to program connections that would

imply the not supported CFI ports.

The following points require specific attention:

1. During power up the EPIC-S must be supplied with an external Hardware Reset.

2. Register bit OMDR:CSB may be programmed to high (switch off standby of CFI

interface) only after a Control Memory reset procedure with MACR:CMC3..0 = 0H.

3. The pins not available with respect to the EPIC-1 (PEB 2055) must not be

programmed as outputs.
