This section has been recently updated for ChipWhisperer 5. The previous version can be found here: https://wiki.newae.com/V4:CW1173_ChipWhisperer-Lite/XMEGA_Programmer
The "GLITCH" port is used for voltage glitching. It's connected to two MOSFET elements, as the following figure shows:
The CW1173 glitch output can be commanded to turn on either of those MOSFETs via scope.io.glitch_hp and scope.io.glitch_lp fields:
scope.io.glitch_hp = True #enable high power glitch
scope.io.glitch_hp = False #disable high power glitch
scope.io.glitch_lp = True #enable low power glitch
scope.io.glitch_lp = False #disable low power glitch
Be careful using this feature, as you don't want to short the MOSFETs for too long. It's also possible to damage the ChipWhisperer-Lite by burning these MOSFETs up if used incorrectly.
