#180608 - Diving into the AT89S52 Responding to: ???'s previous message |

so, I can write 1 to IE0 or IE1
and the interrupts will happen? I read the datasheet, below http://www.atmel.com/dyn/resou...oc1919.pdf there's no detailed information there. and this, is not my homework. I just don't have the hardware to do the test. oh yeah, I'm definitely a noob. I don't even know what "bible" you all mention in the post. Not sure if you saw the embedded hyperlink in my post, so I have included Atmel's '8051-bible' web address for clariy: http://www.atmel.com/dyn/resources/prod_documents/doc4316.pdf Before diving into the AT89S52, I suggest you read through the following: 1.) Latest version of Atmel's own '8051-bible' (given above) which outlines in detail what one can expect from their 'baseline' 8051 core. 2.) Atmel (latest-revision) specific AT89S52 product datasheet (to which you've linked), which describes any features/enhancements not found in a 'baseline' 8051 core i.e. increased IRAM/XRAM, EEPROM storage, ADC's, PWM's etc. The other main function of the document, of course, is to provide electrical/thermal/physical characteristics and limits etc. Now, as others have already asked: What would you like to achieve? Perhaps (most likely) there's a better way.. Regards, Valentin Angelovski PS: I have never used the interrupt event flags in the manner which you describe, for event indication purposes maybe, but not as a direct interrupt trigger! |
