Web2 days ago · • The 8051 C compilers have extensive support for the 8051 interrupts with two major features as follows: – 1. They assign a unique number to each of the 8051 interrupts, as shown in Table 11-4. – 2. It can also assign a register bank to an ISR. This avoids code overhead due to the pushes and pops of the R0-R7. 5 Example 11-14 (1/3)
