26.4.6.2.2 Mode 1: PTGITM[1:0] = 0b01 (Continuous Edge Detect without Step Delay at Exit)

In this mode, the selected trigger input is continuously tested starting immediately after the PTGWHI or PTGWLO command is executed. When the trigger edge is detected, the command execution completes.

Regardless of whether the step delay counter is enabled or disabled, the step delay will not be inserted after the command execution has completed.

Note: The edge detect logic is reset after the command execution completes. To be detected, the edge may therefore occur during the PTGWHI or PTGWLO command execution.

Figure 26-4 shows an example timing diagram of Mode 1 operation.
