•
Use External Interrupts - Enable the use of external interrupt inputs.
•
Number of External Inputs - Select the number of used external interrupt inputs.
•
Level or Edge of External Interrupts - Select whether the input is considered level
sensitive or edge triggered. Each bit in the value corresponds to the equivalent
interrupt input. When a bit is set to one, the interrupt is edge triggered, otherwise it is
level sensitive.
•
Positive or Negative External Interrupts - Set whether to use high or low level for
level sensitive interrupts, and rising or falling edge for edge triggered interrupts. Each
bit in the value corresponds to the equivalent interrupt input When a bit is set to one,
high level or rising edge is used, otherwise low level or falling edge is used.
•
Use Low-latency Interrupt Handling - Enable the use of low-latency interrupt
handling.
Parameter Values
To obtain an I/O Module that is uniquely tailored a specific system, certain features can be
parameterized in the I/O module design. This allows for configuring a design that only uses
the resources required by the system, and operates with the best possible performance. The
features that can be parameterized in I/O Module designs are shown in
I/O Module v1.02a
