Set K60 M3 pin as VREF_OUT

Teckna — Fri, 20 Jul 2012 17:24:56 GMT

Hi,

i'm using MQX 3.8, CW 10.2 and a custom board based on K60N512.

I should set M3 pin of K60 as VREF_OUT mode but i don't find the way.

What are instructions to do it?

Can you help me?

Thanks!

Hi teckna,

where is the problem?

Chapter 37 describes Voltage Reference and it's registers. Use bareboard approach to set registers

Hi Kojto,

my problem is not setting voltage reference but how set the pin M3 for VREF_OUT configuration.

M3 pin has 4 possible configuration:

1)VREF_OUT

2)CMP1_IN5/
3)CMP0_IN5/
4)ADC1_SE18

It's not a PTx pin, then i can't use bit ALT to set its configuration.

Regards,

Hi Teckna,

M3 pin is dedicated output. Just leave default settings (ALT 0) and enable VREF module and necessary registers and it should be running.

Hi Kojto,

in my application VREF module is disabled.

My VREF_OUT signal is driven by an external voltage reference source via the VREF_OUT pin.

I want to be sure that in my condition M3 pin configuration is as VREF_OUT but i am not able to find its configuration register.

May you indicate me the register?

Many Thanks.
