Reset Sequence

ULINKpro's reset sequence is device-specific. To reset most devices, ULINKpro asserts the JTAG RESET signal (pin 3 [TRST] on ARM Standard JTAG connectors), then attempts to stop the device immediately.

Some ARM devices do not support an immediate stop after a reset, and instructions are executed before ULINKpro can send the stop command. For these devices, ULINKpro stops the CPU as soon as it gets control, then sets the program counter (PC) and stack register (CSPR) to simulate an immediate stop after reset.

The following knowledge base articles describe side effects that potentially can happen when resetting ARM devices:
