Jul 21, 2011 · A microcontroller has several sources of interrupts, which can be external or internal. The most common internal interrupt sources are timers, EEPROM, ADC module, and comparator. External interrupts originate in peripherals and reach the microcontroller through one of its pins and associated ports. The low threshold can be found in the datasheet in the “Electrical Characteristics” section as V IL and the high threshold is V IH. Output Modes Push-Pull. A push-pull output is another aptly-name GPIO mode. The pin as the ability to “push” the signal high or “pull” it low. It does this using a pair of complementary transistors.

Need a strong device that can control other devices in your circuit design? Look no further. This PIC16F877A-E/PT microcontroller manufactured by Microchip Technology will meet and excel your needs. This microcontroller has a minimum operating temperature of -40 °C and a maximum of 125 °C. It has a maximum clock speed of 20 MHz. A microcontroller's internal ADC was inadequate to measure its own supply rail, so a circuit using standard discrete components was devised to do this with just one pin of the IC.
