Microcontrollers Memory Organization and Types

WebMapped memory regions, also called shared memory areas, can serve as a large pool for exchanging data among processes. The available subroutines do not provide locks or access control among the processes. Therefore, processes using shared memory areas must set up a signal or semaphore control method to prevent access conflicts and to keep WebThere are six interrupts including RESET in 8051. When the reset pin is activated, the 8051 jumps to the address location 0000. This is power-up reset. Two interrupts are set aside for the timers: one for timer 0 and one for timer 1. Memory locations are 000BH and 001BH respectively in the interrupt vector table.
