Hi,

 

In FRDM-KL46Z pin 21 of PK20DX128VFM5 is connected to pin 52 of KL46 MCU. I have been following  Tutorial: Using the FRDM-KL25Z as Low Power Board | MCU on Eclipse  and I realised that J14 should be disconnected but this is working for FRDM-KL25 and for FRDM-KL46 there is no jumper to make them disconnected. 

 

I looked at the schematic and I found this two:

 

For FRDM-KL25

 

and for FRDM-KL46

 

How can I disconnect pin 21 of PK20DX128VFM5 to pin 52 of KL46 MCU?

Thanks,

Bee Zee
