Dear Fellow Engineers
Can anyone please advise that if we are using SWD programming is the RESET pin absolutely required? In other words can we get away without using this pin when SWD programming? The reason why I ask is that the coin cell circuit design in the datasheet only shows SWD connections NOT serial and the RESET pin is NOT connected? I understand the SWD standard states that the RESET is required but I also understand that with some devices this is not always the case?
Also, we intended to use a Segger J-Link JTAG/SWD programmer to program the DA14580, other than managing the 6.8V VPP is there anything to be particularly aware of when programming the part in this way?
I was also wondering if perhaps anyone had a connection diagram with the required pins shown for programming the device, I understand there is a serial method also?
