13.2.6.8 Reset Control
When in Debug mode, debug probes can reset the device (core and peripherals) via the NRST pin or the Reset Controller (RSTC) registers.
When in JTAG Boundary Scan mode, the device can be reset via the NRST pin or the IEEE 1149.1 reset method.
Important: In Debug mode, resetting the core and peripherals by setting the
SYSRESETREQ bit in the AIRCR via the SW-DP/JTAG-DP interface is not possible.
