Configuration Modes such as

full duplex, master and slave

mode.

If errors are detected in the

8B10B coding rules ERRL will

ERRL O Error Latch

be forced high.. ERRL will be

reset low if the device is forced

out of synchronisation e.g.

PORB = 0.

ERRC will go high coincident

with each error detected in the

89

ERRC O Error count 8B10B coding rules. Errors may

be accumulated by means of an

external electronic counter.
