Random 1 logical state in MC60's PCM Pins

Hi
i face a problem every time i want to turn MC60 on , PCM_OUT , GPIO3 & PCM_IN Pins randomly
reach to 1 state and randomly they turn off.
i want use this pins as GPIO not PCM
MC60 ?
i think if turn of PCM function and store it in internal flash may fix this problem but i don’t know how can i do this thing.

Hi
Are you the open sdk version? If yes, you can register the pin pin as gpio. For details, see example_gpio.c. Note the enumeration of available pin pins. Only some pins can be configured

after some researches i find out that it’s normal for these type of modules that have 1 logic state when they are turning on or off. if you want to use for example a relay with its GPIOs you should use something like a stablizer circuits.
