How do I Generate D and Z Interrupts?
2006-10-30 10:37 AM
Someone please help!
I am working with the ST72141 (ST72E141K2) through an emulator and I'm trying to generate a D interrupt (MISR = 0x04) and Z interrupt (MISR = 0x02) and am having no luck. Can anyone tell me what is the simpliest way to generate these 2 interrupts with the hardware? I have no trouble generating a Commutation interrupt (MISR = 0x01) and I believe the D and Z events follow in that order. How I am Generating the Commutation (CI): Here are the steps taken with the Visual Developer: set MIMR = 1 set MCRA = 0 set MTIM = 1 set MCOMP = 3 set MCRA = 0x80 step through the program until MTIM = MCOMP (2 steps in this case) once MTIM = MCOMP --> MTIM is reset = 0, MISR = 0x01 (CI!) from there, what is the best method to generate a D event and then from there to generate a Z event? And if I'm on the wrong track, please just tell me where to start. I thank you very much in advance for your help! Wayne
