Last word output during BC mode indicates last data word of the current
message transfer has been transferred on the parallel bus.
Output signal which indicates an error occurred during the current message
sequence.
Bipolar serial data output to positive input of bus transceiver.
Bipolar serial input from negative output of bus transceiver.
Parity bit input for RT address.
Bit 1 of RT address input.
Bit 3 of RT address input.
System reset input - resets all inputs in module.
Bipolar serial data output to negative input bus transceiver.
Bipolar serial data input from positive output of bus transceiver.
16MHz TTL clock input.
Signal ground.
Cycle enable input Logic "0" initiates bus controller message transfer operation.
New bus grant output from RT indicates beginning of message transfer
sequence.
Built in Test enable output indicates RT is transferring BlT word on internal 16 bit
bus.
Write enable output for control of subsystem memory.
Bus request input in response to DTREQ. Allows BC/RT to transfer data to
subsystem.
Loop error output. Logic "0" indicates failure of loop back transmitted data.
Subsystem busy input for RT status word.
Illegal command input to RT, used to block RT response to an illegal command.
Increment output pulse. Goes LOW at the completion of each word transfer
to/from subsystem. Can increment external address counter.
Frame ground electricity isolated from signal ground
LSB of current command word count field.
Bit 2 of word count field.
Bit 4 of word count field.
Transmitter inhibit output signal for Channel A.
Latched Mode Command. Logic "1" indicates current word command is a mode
code word, WC0-WC4.
Factory test point. Do not connect.
