minimum Pin requirement for KL03Z

Hi, I'm using the KL03Z MCU for one of my project. As space is very limited on the board, i want to keep pin count to a minimum.

So my question : is it possible to program the MCU using only VCC, GND, SWDIO and SWCLK pins? I have seen that FRDM boards and OpenSDA use reset line for Debug and does not seem to work without it connected. Any idea which debugger i could use working with the minimal SWD configuration specified in de documentation : "2-pin serial wire debug (SWD) provides external debugger interface" found here

 

regards,

 

Ben
