Appendix E. Waveform of each mode

PCI-1755 provides two types of transmit modes for sample input data from external device

to the PCI-1755 or output data from PCI-1755 to external device.

Normal Mode

Handshaking Mode

Normal Mode of Ultra-Speed Digital Input

In Normal mode of PCI-1755, you can start to transmit the data from external device to the

PCI-1755 by start signal or stop it by stop signal. You can generate start or stop signal by

software command, external trigger via

DI_STR

DI_STP

and pattern

When PCI-1755 gets the start signal, it will start to receive data from external device at

next clock (Point A). When PCI-1755 gets the stop signal, it will stop to receive the data at

next clock (Point B).
