Full Confirm This bit is set when the Request was for Full Conformation
Unexpected Frame Status This bit is set when the frame status does not match the value
programmed in the Request Expected Frame Status Register This applies only to Full
Confirmation
Parity This bit is set when a parity error is detected in a received frame Parity is checked from FC
to ED inclusive if the FLOW bit in the Mode Register is set
Exception This bit is part of the MACSI’s hierarchical status reporting It is set when an exception
occurs during confirmation An exception is any one of the nine error or exception codes described
in the RS Field The RCHN’s EXC bit in the Request Attention Register is also set
Ring-Op This bit is set when the ring changes operational state after transmission but before all
returning frames have been confirmed
