Using Debug and all TSI channels ?

yd_sersa — Thu, 28 Feb 2013 10:24:47 GMT

Hello,

For a new project, I need to use 16 capacitive's keys and I want to use a KL25Z. But I've seen that SWD pins and TSI channel are mux. Is there a way to debug this microcontroller with all TSI channels active ?

Regards,

Y.D

Hi,

Unfortunately SWD Interface is fixed to pins PTA0 and PTA3. There is no way to debug and use TSI pins (PTA0 and PTA3) at the same time.

This is because:

PTA0 can be TSI0_CH1 and also SWD_CLK. This depends of MUX field configuration. SWD_CLK is used to perform debug.
PTA3 can be TSI0_CH4 and also SWD_DIO. The last one is used to perform debug.

Hope this helps.

Y.D,

How is the project going?

Keep us posted! :smileywink:

Hello,

I've no other choice, in debug I'll use only 14 capacitive keys.
