56 Function Block and Operation Theory
3.9 Application Function I/O
PCIe-7350 features eight AFI (Application Function I/O) lines.
These bi-direction digital I/O lines allow you to route I2C, SPI, trig-
ger, event, handshaking, and clock signals to/from the SCSI-
VHDCI I/O connector. The following table lists the supporting func-
tions of AFI lines and the corresponding pin out.
