Config. via network FOSL3 - 0
FLAG OUTPUT
Tying the shared pin PGS2 to high level configures the upper four bits of port D to be FLAG OUTPUT port.
When the FLAG OUTPUT configuration is used, the OUTPUT PORT feature using the OUTPUT DATA
packet is not available. The flags start to drive within two system clock cycles after the de-assertion of
reset.
The FLAG OUTPUT port outputs six different flags: MSB (FO3) always outputs nRCNERR; the lower three
bits (FO2 – 0) output a set of three flags that is selected from five flags using the bits FOSL3 – 0 that are
configured through network.
