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!
