Pin 15, 17, 19 - configured as output with 1x push pull. They are used for testing purpose.
All comparators positive inputs are connected to the Pin 6 analog input. When the voltage on the positive input is higher than the
voltage on the negative input, comparator will set logic “1” on its output. ACMP0 positive input is 200 mV, ACMP1 is 500 mV, and
ACMP2 is 800 mV, creating 4 states:
• All LEDs are off
• LED_A is on
• LED_A and LED_B are on
• All LEDs are on
If Pin 2 logic level is set to “1”, these states will transform into:
• All LEDs are on
• LED_A and LED_B are on
• LED_A is on
• All LEDs are off
