Abstract
This document describes the differences of PEF 22558 E, OctalFALC
relative to the QuadFALC
1
The number of receive and transmit channels has been increased from four to eight. All
channels can be configured and used independently.
To enable a seamless transition from QuadFALC
a compatibility mode is provided. This mode allows software written for the QuadFALC
to be used with the OctalFALC
For new applications, a number of additional features and enhancements are provided.

2.1
The OctalFALC
mode usable with QuadFALC
To enable use of PG-LBGA-256-1 package the number of multifunction ports is reduced
to three in receive and two in transmit direction per channel. Furthermore RCLK signals
are provided on multifunction ports instead of separate pins.
To ensure software compatibility unused registers (for example PC4) still exists but are
not used.
