About Flow Control Modes (Handshake)
Five flow control modes are available for Digital I/O operations. Some
modes use one or more of the three flow control lines: I/O Direction,
PFLG, and PCTL. Select the flow control you need for your digital input/
output applications.
Note
The polarity of the flow control lines is assumed to be positive (the
default) in the following diagrams and discussions.
