WebThe examples of 8-bit microcontrollers are Intel 8031/8051, PIC1x, and Motorola MC68HC11 families. The 16-bit microcontroller performs greater precision and performance as compared to the 8-bit. For example, 8-bit microcontrollers can only use 8 bits, resulting in a final range of 0×00 – 0xFF (0-255) for every cycle. Web8085 supports multilevel interrupts. So, the interrupts are classified as: Hardware Interrupt: These interrupts are basically associated with peripheral devices generated at the time of data transfer between I/O device and microprocessor. An external device generates interrupt by placing an interrupt signal over the pins of the microprocessor. Web1 apr. 2016 · Table 2: Interrupt latency compare between 8051 and Cortex-M processors.
