Pin Description (Cont.)
Manchester Error - This line will pulse low if a Manchester
error is detected by the decoder.
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.
Valid Data - This line will pulse low when a valid data word is
received.
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.
Loop Test Enable - Enables automated self-test when low.
Normally high.
Loop Test Trigger - When pulsed low while LTEN is low
automated self-test is initiated. LTEN pulse width should be
100ns < PW < 5µs.
Bus A Transmit/Receive - HIGH output to the primary side of
the coupling transformer that connects to the A Channel of the
1553 Bus.
Bus A Transmit/Receive - LOW output to the primary side of
the coupling transformer that connects to the A Channel of the
1553 Bus.
Bus B Transmit/Receive - HIGH output to the primary side of
the coupling transformer that connects to the B Channel of the
1553 Bus.
Bus B Transmit/Receive - LOW output to the primary side of
the coupling transformer that connects to the B Channel of the
1553 Bus.
