GPIO Pins used by peripheral bootloader SCI-A in TMS320F28377.

Charles T

I am having a confusion on the GPIO Pin numbers. The Technical reference manual for this DSP gives 2 options for configuring SCI(attaching the picture). But in Datasheet the function of GPIO28 and GPIO29 is reversed like GPIO28- SCIRXDA and GPIO29- SCITXDA. Please clarify which one is corrrect.

Hi Charles,

As mentioned in "Table 4-4. GPIO Muxed Pins" and "Table 4-1. Signal Descriptions" of device datasheet GPIO28 is SCIRXDA and GPIO29 is SCITXDA. We'll correct the discrepancy in these documents. Thanks for your valuable feedback.

Regards,
Vivek Singh
