If I can do that... How to set ICW4 ? Thanks again.
The 8259 was specifically designed to support the 8086 interrupt sequence. Why would you want to use it with an 8051?
Hi Andy Neil: Nice to hear you again. Since I want to extend interrupt sources and only want use one 8051, but the 8259 is one of my choices. Do you have any suggestions? Best regards.
Find a different 8051 variant with sufficient interrupt sources? Add a CPLD?
why "Hi Andy Neil" with the same question? Do you want the naswers in stereo? Erik
Thank you for both of you. let me try.
