MANER

OUTPUT

Manchester Error - This line will pulse low if a Manchester

error is detected by the decoder.

DBCREQ

OUTPUT

Dynamic Bus Control Request - This line will pulse low when

the status reply for a mode code Dynamic Bus Control has

finished where the accept bit was set.

VALD

OUTPUT

Valid Data - This line will pulse low when a valid data word is

received.

DRVINH

INPUT

Driver Inhibit - Selects on-line or off-line testing during

automated self test. When high self test is on-line. Must be high

when LTEN is high.

LTEN

INPUT

Loop Test Enable - Enables automated self-test when low.

Normally high.

LTTRIG

INPUT

Loop Test Trigger - When pulsed low while LTEN is low

automated self-test is initiated. LTEN pulse width should be

100ns < PW < 5µs.
