Mode Select input - logic "1" for RT mode, logic “0” for BC mode.
Monitor mode enable. When unit is operating as a BC, a logic “0” will select monitor
mode.
Output signal in RT mode that indicates status word is being transferred on the
internal bus.
Indicates No Response Timeout has occured during BC and RTU (RT to RT transfer).
Output in RT mode indicating the DMA transfer did not occur in time to allow proper
operation on the 1553 bus.
Input signal used to set DBACCEPT bit in status register for response to a valid mode
command on the 1553 bus.
Input which controls the SSFLAG bit in the status register.
Input which controls the service request bit in the status word.
Output signal indicating the RT is currently in a message transfer sequence.
Input which controls the subsystem error bit in the status register.
Factory test point. Do not connect.
WC bit 1 - latched output of command word.
WC bit 3 - latched output of command word.
Transmitter inhibit output for channel B.
Output indicating T/R bit of current command word in RT mode.
Output indicating current selected channel (0 = Channel A).
Chip Select output for subsystem memory control.
Output Enable output for subsystem memory control.
Output signal used to initiate transfer to/from subsystem.
+5 Volt DC input.
Least significant bit - 16 bit parallel data bus.
Bit 2 of data bus.
Bit 4 of data bus.
Bit 6 of data bus.
Bit 8 of data bus.
Bit 10 of data bus.
Bit 12 of data bus.
Bit 14 of data bus.
Last word output during BC mode indicates last data word of the current message
transfer has been transferred on the parallel bus.
