4.9.2 Cancel logic for SBO mode
In the SBO control mode, the reception of a cancel command can be possible when the cancel
conditions are satisfied, the function can discard the select command; finally, the operation
returns to the initial stage (i.e., “wait for a command”).
(i) Receiving “Cancel” from the remote-end
Figure 4.9-21 depicts the cancel command procedure for a cancel command initiated from the
remote-end.

Figure 4.9-22 depicts the cancel logic when a “Cancel command (Remote-Cancel)” signal is
applied to the TPOS01 function. The input-point “DEV01_CONTROL_REQ” is the same as
that for the “Selection command P1 (Remote-P1-Control)” signal.
