Watchdog Handling
- The device has a watchdog WDT.
- The watchdog is not fed during flash programming.
Device Specific Handling
Connect
The connect sequence of PMG1 devices is very time critical and is performed from the J-Link's side directly in either one of these 2 modes:
- Reset mode:
J-Link toggles the XRES line and then sends SWD commands.
Reset mode is not supported by EZ-PD™ PMG1-S0 MCU devices because they do not have an XRES pin.
- Power Cycle mode:
J-Link powers on the target and then starts sending the SWD commands.
This is the only mode supported by EZ-PD™ PMG1-S0 MCU devices.
Reset
- The device uses custom reset via AIRCR.SYSRESETREQ and halt at application entry point.
Limitations
Attach
Attach is not supported because the J-Link resets the device on connect.
