Hello, I have a problem in sending characters on sci. For example I send "W1=10\r" every one second. After one hour the command is not correct. On the TX pin i...
... It's not very clear what you have on TX pin after hour. Is it ~1s pause, then '\r' char, then some pause and "W1=10" chars sequence? All chars must have...
I am using the 9S12A32 serial port and I want to use address mark wake up. I have set the SCI for 9 bits, one stop bit, no parity, interrupts on, transmitter...

... I think you are saying that the 1-second delay has moved... should be after the '\r' but after an hour it is delaying one second after the "10" instead. ...
... I've fixed some things. Big mistake was I had changed the relocation (INITEE), and accidentally was disabling EEPROM. It demonstrates easy subroutines to...
I've come up with a question in the new Flash/EE on S12. My example code proved that I can program more bits in EEPROM Flash that has already been programmed....
Hello Jim, ... The problem is not the delay. The problem is that the program send to the sci W1=10\r and after several hours (it depends of what??), the...

Hi again //Envoie des caracteres ... The TxBavail0-- is only one instruction (Dec instruction). I forget to say that The interrupt routine is made by the...

Hello Edward, ... Now i understand very well my problem! Thank you!! Using semaphores seems to be good. Do you know where i can find example of it? Thank you...
... There are 8 semaphores available in XGATE module. You should read about them in XDP512 chapter 6 XGATE, 6.4.4 Semaphores. There's Fig 6-22 Algorithm for ...

Hi, I have been pursuing the same or similar problems for a number of years with programming HCS12Dx. We have a few parallel Multilink P&E BDM interfaces and a...
Gary, ... T8 bit in SCIDRH, counting from zero, is bit 6 (mask 0x40), counting from 1 it's bit 7. If it was just a typo and you indeed are using SCIDRH...
Andrew, I don't know much about Compod12, but I'm sure Multilink doesn't program parts. Multilink is just an interface between PC and your target and I believe...
Hi, What I understand you have problems on receiver side. But: Setting the receiver wakeup bit, RWU, in SCI control register 2 (SCICR2) puts the receiver into...
Thanks Edward, I can fix the two clock frequency's, and that is how I run Zap. Strangely also using ComPod12 on a HCS12D target also makes it unusable by Zap...
I think I figured out the problem. The bootloader code runs from RAM and uses the INITRM register to overlay the flash bootblock with RAM. Apparently, a COP...
Jeff, No, COP reset should reset almost everything. The exception should be just a couple of reset source related bits like PORF. I hardly believe you are ...
... I don't believe either that it has to do with COP and INITRM, but I think we are losing sight of the actual problem. What does INITRM have to do with...
... Thank you mucho. Everything you said makes sense except this, "simply not allowed". Perhaps someone has trouble with the English lanquage, but it is...
... Concerning the question why INITRM might be related: Perhaps the difference is that you are making it "work" by writing to INITRM after the COP reset? I...
