Description

Reset Receiver 1.

Used to reset Receiver 1 at any time. Assert and remove a “1” to reset Receiver 1.

Note: Reset will destroy any word being received at the time of the reset.

“1” = reset. Reset must be removed to enable receiver. Receiver function inhibited by a high

level on reset.

Reset Receiver 2 – Same as for receiver 1.

Establish parity.

1 = ODD; 0 = EVEN. Both receivers and the transmitter must use the same parity.

Set Receiver 1 Data Rate: 0 = LOW (12-14.5 kbps); 1 = HIGH (100 kbps).

Set Receiver 2 Data Rate: Save as for Receiver 1.

Set Transmitter Data Rate.

Same as for Receiver 1.

Note: Data rates for the transmitter and individual receivers are independent.

Description

“1” = Receiver 1 has received word.

“1” = Receiver 1 word has a parity error.

“1” = Receiver 1 error (32 bits received before idle state).

“1” = Receiver 2 has received word.

“1” = Receiver 2 word has a parity error.

“1” = Receiver 2 error (32 bits received before idle state).

“1” = Transmitter buffer and FIFO entirely empty (Up to 5 words may be written to transmitter). .
