C166 |  XC164 CAPCOM6 unit Daniel Lid Hi,
I'm new to the XC164 and microcontrollers.
I'm trying to setup the Capcom6 unit for a 100% PWM output on COUT60, 61 and 62. In debug mode (uVison2) the registers (under Peripherals T12, T13, CAPCOM6) are not updated when I single step my code. Could anyone help me with the right settings?
Best regards
/Daniel |

C166 | RE: XC164 CAPCOM6 unit Stefan Fricke Please have a look to INFINEON webpage
- look for the APPNOTES
AP1672 Dead Time Generation with CAPCOM6
and
AP1673 Details on CAPCOM6
this was usefull to me, but have not tried with the new XC16x derivatives

C166 | RE: XC164 CAPCOM6 unit Gavin Pugh Hi,
I've got exactly the same problem! Did you find a solution to this? If so could you let me know!
Thanks, Gavin. |

C166 | RE: XC164 CAPCOM6 unit Daniel Lid Hi,
I don't know which compiler version You use, but according to Keil, it wasn't possible to simulate the CAPCOM6 unit of the XC16x family at that time and that it would be a part of a software upgrade (April 2003). I haven't tried this update though, so I don't know if it works now.

C166 | RE: XC164 CAPCOM6 unit Stefan Fricke Hi Daniel,
the appnotes are quite good, but take care, since the restrictions for 100% and 0% duty cycle are not valid anymore.
A better description you cand find in the preliminary version of XC164, where this version is available on the web.
CAPCOM6 support for XC16x is planned in KEIL's simulator approx. march/april 2004.
You can simulate with old CAPCOM6 simulator dll, but this is tricky and you have translate some registernames to the new one
according the manual.
zero-match & parallel compare-match --> active state (CC6xR=0)
zero-match wo compare match -->
passive state (T12=0)
A duty cycle of 0% is done as I know with reload of '0' and zero match without compare match enabled for T12.
100% you can reach for my understanding by
programming the wished period value + 1 and enabling both matches.
For details have a look at peripheral manual.
(xc164_um_per_v2.0._2003_12_pre_release)
For some other reasons I have 2 examples written for simple edge aligne PWM and
center aligned PWM dealing with shadowtransfer.
(But not 0% and 100% duty cycle).
If you are interested I can share the code.
Best regards Stefan |

C166 | RE: XC164 CAPCOM6 unit Gavin Pugh Hi guys,
Thanks for the update. I am using uVision 3 with the V5.00 compilier (the latest versions at time of writing).
It is not easy to realise that a periferal isn't simulated. The other misleading thing is that the Timer12/CAPCOM6 debug windows don't update on either simulated OR ULINKed processor conditions. I thought I was going mad!
The irony is that my code for timer 12 was working all along - To prove this I repeatly read the T12 counter into a variable then watched the variable count up and down in the debug enviroment.
This seems to be the only way to debug T12/T13/CAPCOM6 stuff in ULINK for the time being. |

C166 | RE: XC164 CAPCOM6 unit Stefan Fricke Hi Gavin,
that's one of the ways. I dealt with old CAPCOM6 (tricky) and if I got it working,
I had a little bit more understanding.
For debugging purposes I misuse a starterboard with hardwired CAPCOM6 outputs and an oscilloscope to see, whether the signalforms are the expected one or not.
For simulation your way is surely more practicable.

C166 | RE: XC164 CAPCOM6 unit Stefan Fricke Hi Andreas,
I sent you 2 projects for startup.
1 Edge Aligned Mode, 1 Center Aligned Mode.
( Simply output some signals to an oscilloscope )
