Port pin configured as ADC input at POR?
I have the LPC824.
I use PIO0_20 as a simple port pin set to output that I manually change its status in code - Chip_GPIO_SetPinState(.....) - at certain specific times.
The port pin was not doing any action at all.
After some delving in debug mode, I found that in the SVM register ADC_6 was set to 0 , thusly enabling ADC_6.
I don't set ADC_6 to be enabled in my code. ADC_6 at POR should be disabled by default (set to 1).
Has anybody else seen this?
