C51: Interrupt Vector Numbers
Information in this article applies to:
Where can I find a list of the interrupt vector numbers to use with C51?
Calculate the interrupt number for C51 interrupt vectors as follows:
(interrupt_address - 3) / 8
So, for interrupt address 33h, the interrupt number would be:
(33h - 3) / 8 = 30h / 8 = 6
Refer to Application Note 103 for more information about interrupt vectors and C51.
