message transfer has been transferred on the parallel bus.
30
MSGERR
O
Output signal which indicates an error occurred during the current message
sequence.
31
TXDATA A
O
Bipolar serial data output to positive input of bus transceiver.
32
RXDATA A
I
Bipolar serial input from negative output of bus transceiver.
33
RTADP
I
Parity bit input for RT address.
34

40
GROUND
-
Signal ground.
41
BCSTART
I
Cycle enable input Logic "0" initiates bus controller message transfer operation.
42
NBGRNT
O
New bus grant output from RT indicates beginning of message transfer
sequence.
43
BITEN
O
Built in Test enable output indicates RT is transferring BlT word on internal 16 bit
bus.
44
WR
O
Write enable output for control of subsystem memory.
45
BUSGRNT
I

47
SSBUSY
I
Subsystem busy input for RT status word.
48
ILLCMD
I
Illegal command input to RT, used to block RT response to an illegal command.
49
ADRINC
