I want to create an interrupt function. So I have to know the interrupt number and I have to select the register bank. My question is, which register bank I must select and why??? Where can I get information about this problem? Thank you for answers. andy
There is a good explanation of register banks and when and why to a different bank for interrupts. See GS51.PDF chapter 9, page 184 (document version 02.2001) Then search for "register bank" in the C51.pdf file.
