70 Operations
Handshake
PCIe-7360’s Application Function I/O (AFI) can be configured as
handshake mode (DI-REQ/DI-ACK/DI-TRIG/DO-REQ/DO-ACK/
DO-TRIG) to communicate with an external device using an
acknowledge signals to request and acknowledge each data
transfer. The handshake mode can ensure the data transfer with-
out loss.
For the digital pattern acquisition using handshake, through
DI-REQ input signal from external device and DI-ACK output sig-
nal to the external device, the digital input can have simple hand-
shake data transfer. (See Section 3.7 Operating Modes)
For the digital pattern generation using handshake, through
DO-REQ output signal to the external device and DO-ACK input
signal from external device, the digital output can have simple
handshake data transfer.
For the PCIe-7360 to communicate with peripheral devices using
handshake, verify that the DUT and the PCIe-7360 have compati-
ble timing.
