I/O Function
I Transmitter data input. 1 = mark or stop bit. 0 = space, start or break
signal.
O Transmitter data output. Output data is synchronized to the
synchronous timing signal TXC (pin 4). 1 = mark. 0 = space.
I Asynchronous mode. XASY = 0 Asynchronous transmission, XASY = 1
Synchronous transmission. In synchronous transmission the converter
is totally bypassed in both directions: TDI = TDO, RDI = RDO
I Higher speed signalling timing. XHST = 1 normal synchronous to
asynchronous conversion (CCITT V.14). XHST = 0 asynchronous to
synchronous conversion with higher speed synchronous timing (TXC,
RXC). TXC and RXC timing must be 1-2% higher than the normal bit
rate in order to allow some overspeed in the asynchronous data.
On the receiver side the RX buffer is deleted and the synchronous
data RDI is directly connected to the asynchronous output RDO.
O Receiver data output. RDO is the received data converted back to
asynchrnous mode.
1 = mark or stop bit, 0 = space, start or break signal
I Receiver data input. 1 = mark, 0 = space. The received data must be
synchronized to the receiver timing RXC from the synchronous
channel (pin 15).
I Receiver timing (MAS9138 only). Receiver square wave timing from
the synchronous channel. The received data RDI must be
synchronized to the rising edge of RXC.
