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 PMG1-S0 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.
Therefore the target device needs to be supplied via Pin 19 of the J-Link and Pin 1 also needs to be connected to pin 19 of the J-Link.
Make sure to set VSupply (pin 19) correctly before connecting it to the target board.
This is the only mode supported by PMG1-S0 devices.

A device with reconfigured SWD pins runs automatically the acquire sequence to get control of the SWD pins for debugging back.

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.
