Figure 30: ACMP Properties
Pins 15, 17, 19 - configured as output with Push-Pull 1x. 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, comp
arator 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
