Tool/software: Code Composer Studio

Hi,

In a program, I need to completely disable the generate SPI through HalCoGen during program operation.

Finally, I would like to cancel the spiInit() function; ...

How can I do this? Thank you in advance !

Hello,

Under "Driver Enable" tab, deselect the SPI drivers: "Enable MIBSPI Drivers" and "Enable SPI Drivers"

After unchecking SPI, the HALCoGen will no generate spi.c and mibspi.c.

Thank you for your answer.

Unfortunately, you did not understand the question correctly or I misspoke.

I want to disable the SPI while the program is running directly in the software, not in HalCoGen before running the program.

Is that clearer?

You can reset the SPIx module by writing 0 to the nRESET bitfield of the SPIGCR0 register at address offset 0x00.
