Programming header and Debug Header for STM32L073 micro?

[amass.9]

Hi,

I am laying out  aboard with STM32L073. I would like to add a debug header and a programming header. Do you know which pins i should connect  these headers to?

 

I see that PA13 and PA14 are involved in debugging, but which other pins do i also need to include in the header?

[Tesla DeLorean]

VCC and GND

NRST to allow for controlled startup

On CM3,4,7 consider PB3 / SWO, but not supported on CM0(+) parts

[amass.9]

Thanks, by CM3, CM4, CM7, do you mean the Cortex-M thing?

How would i know if i have a CM3 say?

The part number is

STM32L073CBU6 (LQFP48)

It would certainly be stated in the datasheet.

Most likely even in the marketing material; eg,

STM32L0 is Cortex-M0+
