Hello,

I designed a circuit in Eagle for JN5168 MCU based on the reference design in the datasheet: https://www.nxp.com/docs/en/data-sheet/JN516X.pdf
I wanted to ask if I connected correctly the JTAG pins to the MCU. There are currently only 4 pins (excepting VDD and GND) the are connected to the MCU.

For example the SRST pin on the JTAG connector should be somehow connected to RESETN pin of the MCU?
How about TRST, RTCK, DBGRQ or DBGACK pins? Should I connect them somewhere?

JTAG is a 4 pin interface and works with TCK, TMS, TDO and TDI. All other JTAG signals are optional. Check if your preferred JTAG adapter can utilize optional pins and if they are provided by the chip.
