Modifying the Backend Interrupt Vector
The default setting of Core1553BRT creates a 7-bit interrupt vector, which indicates whether or not a
good message was received. It is also used for a transmitter subaddress. If INTENBBR (Interrupt Enable
Bad Block Received) is HIGH, interrupts are generated for good and bad 1553B messages. When
INTENBBR is LOW, interrupts are only generated for messages that are received or transmitted
correctly.
An external interrupt mapping function can be used to add extra information to the interrupt vector
( Figure 7-2 ), such as the received word count. It will also tell you whether the command was broadcast.
The CMDVAL output can be used to generate this extra information; however, it must be externally
latched using the INTLAT signal (INTLAT is an active high enable for an external D-type flip-flop).

Figure 7-2 ? External Interrupt Vector Extender Circuit
The interrupt mapping function below creates vector information, indicating broadcast and the received
word count value. If an extended interrupt vector is then generated, the need for the system to read the
TSW or command word from memory is removed. The interrupt vector provides subaddress, word count
data, and an indication that the message was good. In this case, the WRTTSW and WRTCMD inputs can
be tied LOW.
