NJTRST different from NRST on STM32L412

Using the STM32L412 I use the PB4 for the signal NJTRST of debug connector and the ST-LINK does not work fine (but it works using J-LINK).

We use also H723, H743, L476 and L496 connecting NRST to debug connector. This can be done with L412?

NRST != NJTRST, the latter is a JTAG signal, and won't be used in SWD connectivity mode.

All the STM32 can use NRST / NRESET on the JTAG/SWD headers.
