Output Timing
Output timing refers to the delays involved in exporting internal signals to
external terminals, so they can be used to trigger or time external devices.
These timing parameters include the selection multiplexer in each terminal
plus the delay of the output driver. Figures B-20 and B-21 and Table B-11
describe output timing.
The delays presented in this section assume a 200 pF load on PFI lines and
a 50 pF load on RTSI lines. Actual delays will vary with the actual load.
