SPI C / SCI C not supported for code generation with TI2737x

With PlecsVersion 4.9.6 (64 bit)(and it looks like also v5) we experience an issue when generating code for theTI TMS320F28379D Control card.

For both SPI C and SCI C, they do not seem to be supported by the code generation, although the signals are present on the HSE180 connector.

Is there a way to fix this ?
