PXD 222 Digitizer
B. Run Modes
The digitizer can be set to run in either Continuous or Single-shot mode. This is done through
the function LcPXD222_ConfigureInitiateContinuous.
C. Trigger Modes
The PXD 222 Digitizer supports the following trigger types: EDGE, GLITCH, WIDTH, TV, and
IMMEDIATE.
EDGE: An edge trigger occurs when the trigger signal crosses the specified trigger level with the
specified slope. The trigger level and slope are configured with the function
LcPXD222_ConfigureEdgeTriggerSource.
GLITCH: A glitch trigger occurs when the trigger signal has a pulse width that is less than the
glitch width. The trigger does not actually occur until the edge of the pulse that corresponds to the
specified glitch width and polarity crosses the trigger level. The trigger level is configured with the
function LcPXD222_ConfigureGlitchTriggerSource.
