– The FSC signal can be selected from driven by 3 sources:
– The DCL signal can be selected from 3 sources:
Output: FSC produced by ELIC0 (derived from the selected PFS clock, internally,

Input:
Output: FSC driven by selected PFS ((ELIC0:CMD1:CSS = ‘1’) and

In this case ELIC1 should be programmed to produce its own internal FSC
even though it has no effect beyond the ELIC1 block. ELIC0:CMD1:CSS
and ELIC1:CMD1:CSS must be programmed with the same value.

In this case ELIC1 should be programmed to produce its own internal DCL
even though it has no effect beyond the ELIC1 block. ELIC0:CMD1:CSS
