Memory Output Enable. A Logic 0 used to enable data output from
memory when the 1553 or CPU reads from memory.
Memory Enable Out. Low level output to enable external RAM. Used
with MEMOE to read data or with MEMWR to write data into external
RAM.
Clock Input. 16 MHz TTL clock.
Memory/Register. Input from CPU to select memory or register data
transfer.
Strobe Data. Used in conjunction with SELECT to initiate a data
transfer cycle to/from CPU.
External Enable. Used to load data into external devices.
Read/Write. Input from the CPU which defines the Data Bus transfer as
a read or write operation.
External load. Used to load data into external devices.
Ground A. Power supply return connection for the A channel
transceiver.
XXXXXXXXXXX
-I5V input power supply connection for the A channel transceiver.
XXXXXXXXXXX
Transmit/Receive Transceiver-A. Input/Output to the coupling
transformer that connects to the A channel of the 1553 Bus.

Subaddress/Mode Command Bit 2. B8 (MSB) counter.
Subaddress/Mode Command Bit 4.
Subaddress/Mode Command Bit 3.
Logic 0 pulse indicates receipt of a valid command word which
contains the Remote Terminal address equivalent to the
RTADO-RTAD4 inputs.
RTU (address) Parity Error. Logic 0 indicates RTU address parity (odd
parity: RTADO-RTAD4, RTADP) has been violated.
I/O Data Bus Bit 11.
I/O Data Bus Bit 13.
I/O Data Bus Bit 15 (MSB).
