8 Bit Comparator Logic Diagram. A b a b a. 8 bit timercounter with compare modes one 8 bit high speed timercounter universal serial interface internal and external interrupts a 4 channel 10 bit adc a programmable watchdog timer with internal oscillator and three software selectable po wer saving modes.
Port d serves as analog inputs to the analog comparator. Then we can say that the voltage comparator is essentially a 1 bit analogue to digital converter as the input signal is analogue but the output behaves digitally. This 8 bit data is denoted a.
Asm diagram coding with countersregisters instantiation.
1 byte 8 bits. Lights pattern ucf included. X0 and x 1 indicates that the counter counts up when input x 0 and it counts down. Comparator dc specifications are similar to those of op amps.
