TMS320F280039C: C2000Ware SCI library - Which function to set "SLEEP" bit in "SCICTL1" ?

Forgot to attach this screen shot from the Tech Ref Guide....

Hi MonkeyBuissness,

Which is the function call to set "SLEEP"?
Did I miss it?
Or, is it an omission oversight in the library?

It looks like you are correct and this is an oversight in our implementation. I will contact our software team to get this corrected and provide an update for you on the additions needed by tomorrow or the next day at the latest.

OK. Thanks. I worked around it by adding this line to my code:

    HWREGH(SCIB_BASE + SCI_O_CTL1) |= SCI_CTL1_SLEEP;

Thank you, that will also work.

A lot of people within our software team are out of office at the moment, so it may take longer to provide the updated sci.c/.h files but the HWREGH line should be perfectly fine to use as well.

That's fine. I have a workaround.

However, I found some other requirements that are not covered in the driverlib. I am using RS485 at half-duplex. To avoid SCI Tx data going to the SCI Rx, we disable SCICTL1.RXENA while transmitting. We have done this in other products with TI processors. The older stuff did not use the driverlib. It has a statement like this:

SciaRegs.SCICTL1.bit.RXENA = OFF;

I do not see a library call to accomplish the same thing. There is a call to shut off the whole module but that is not what I need. So, for now, I am adding this line to my code:

HWREGH(base + SCI_O_CTL1) &= ~(SCI_CTL1_RXENA);

I figured that if TI is trying to move users to the driverlib, you might want to add this capability..

Thank you, I agree, it is needed functionality. I will pass this forward to our software team to implement.
