KV31F DAC output during reset

hyunkeenoh — Thu, 02 Feb 2017 18:00:45 GMT

Hi,

What is the voltage level of DAC output pin during and after reset on KV31F?

Because DAC is disabled after reset, I wonder its initial voltage level.

It's hard to find it in the reference manual or data sheet.

Thank you,

Hi, Hyunkee,

As the following figure, the default state of the pin is DAC1_OUT, CMP0_IN4 and ADC1_SE23, in other words, all three module output or input are connected togrther. When DAC is disabled, it's output is in in high impedance, so the pin is an input pin as CMP0_IN4 and ADC1_SE23.

Hope it can help you
