AM2634: MCAN_getTxBufTransmissionStatus clear Tx buffer status bit

Hi Volodymyr,

Due to holiday in India, please expect a delay in replies on this thread until 9/19.

Regards,

Brennan

Hope holiday went well. Are there's any updates?

Waiting with patience...

Please support on my question

Hi, Volodymyr. As the register is read only, it can't be cleared directly by writing at the offset. One way is to clear it this way as mentioned in TRM, but it will put the mcan module in init mode, so it will not help:


If you want to see the current Tx bit status, can create a mask based on bitPos variable and check for that particular message.
I will try to find a fix for clearing the register and update tomorrow. Your patience is highly appreciated.

Thank you for reply. Will wait for your updates

Hi, Volodymyr. Looks lke this register as mentioned can be cleared only when the MCAN_CCCR[1] CCE bit is set. As it's read only, can't be cleared by directly writing at the register.

Thank you for reply and I apologize for delay.

From my side this looks like a bug - was it done intentionally or this can be improved in future?
