Hello

I am using the STM8TL touch IC and need to use the PXS_RFIN pin as an IO to drive a LED ie PA7. If I disable the Prox engine then the LED can be toggled, but if I enable the Prox engine then the LED can not be toggled anymore...The PXS_CR2, NOISEDETEN bit is disabled. Are the any other bits I must set to use the PXS_RFIN pin as a GPIO?ThanksJohn #gpio #pxs_rfin #stm8tl53g4

yip, sorted it. had a sneaky PXS_CR2 register being masked in that I missed ...

so you only need to disable the NOISEDETEN bit
