LANBIC Receive Parity Error Counter Test (#595)
This test is destructive.
The test reads and clears the LANBIC Receive Parity Error Counter on the circuit
pack. This counter is incremented by the circuit p ack when it detects a p arity
error in data received from the Packet Bus.
These errors may be indicative of a c ircuit pack prob lem, Packet Bus problem, or
a problem with another circ uit pack on the bus. This test is useful for verifyi ng the
repair of the problem.
