Interrupt Lines

Each bank has an interrupt line that can be used with memory input or output
operations. When a bank is set to input data, the interrupt line is an output. When
a bank is set to output data, the interrupt line is set to be an input. You can set the
polarity of the interrupt line for input and output operations using the
CONFigure:DIGital:INTerrupt:POLarity command.
You can configure the interrupt line drive mode, output drive level, and input
threshold. These parameters are set for both the handshake lines and interrupt
line on a bank. See

Memory Output Operations

For memory output operations, the interrupt line is sensed and can be used to
start or stop memory output operations. This provides a hardware means to
control the data output.
The SOURce:DIGital:INTerrupt:MODE command sets how the bank will
behave when using memory output. The mode can be set to one of three values:
– STARt: The memory output will begin on the rising edge of the interrupt line.
– STOP: The memory output is halted on the rising edge of the interrupt line.
– GATE: The interrupt line acts a a gate for the memory output. The bank can
When you have set the polarity and mode, enable the interrupt using the
SOURce:DIGital:INTerrupt:ENABle command.
To prevent an unexpected trigger, make sure that the pattern interrupt signal is
NOTE
not floating.

Memory Input Operations

For memory input operations, the interrupt line is an output and is set on a
pattern match or when the memory has been filled. You can set the interrupt line
to be driven or open collector using the SENSe:DIGital:HANDshake:DRIVe
command.

output when the interrupt line is asserted, and will stop when the interrupt line
is de-asserted.
