CCS/TMS320F280049C: Sysconfig missing pinmux options for SCI?

Hello,

I'm trying to help a customer figure out pin muxing for a schematic and wanted to use pinmuxtool/ sysconfig to help with the process, but it seems like the tool is missing pinmux options for the SCI peripheral. For example I'm using the 56 pin RSH package, sysconfig offers me these options for SCIA:

But in the datasheet I see that SCIA_RX can also be muxed to pins, 44, 56, and 31.

Is there something I'm doing wrong, or is there some reason these additional pins don't get reported in syscfg?

Mr. Xu,

Thank you for using the pinmux tool and sharing your question with us. I believe the confusing comes from GPIO# vs PIN#. The pins you have mentioned (44, 56, 31) correspond to the GPIOs shown in the options. Inside the pinmux tool you have an option to enable the PIN number to also show along with the GPIO#s. (available under "settings")

Also please use the even more powerful C2000 SysConfig Utility which not only configures your pinmux, but it also writes C code to configure your peripherals.
