Remote Terminal Address Error. This line goes low if an error is
detected in the RT address parity of the selected receiver. Any
receiver detecting an error in the RT address will turn itself off.
Subaddress. These five lines are a label for the
data being transferred. Valid when INCMD is
low. SA4 is the most significant bit.
Self Test Interrupt indicates that the Initiate Self Test Mode
Command is being served.
Status Update. When held low, causes TF or SSF to appear in
Status Word response to Transmit Status or Transmit Last

Transmit/Receive. The state of this line informs the subsystem
whether it is to transmit or receive data. The signal is valid while
INCMD is low.
Vector Interrupt
Word Count. These Five lines specify the
requested number of Data Words to be received
or transmitted. Valid when INCMD is low. WC4
is the most significant bit.
Write Strobe. Must GO LOW together with DS to perform a write
operation. NOTE: RD must be high.
IN COMMAND. Goes low when the interface is servicing a valid
command. Can be utilized to enable external firm-ware to
illegalize subaddresses and mode command not allowed by
