Please provide an example to calibrate the trim and slope values for the comparator in a PSoC 6
I was not able to find any examples or better documentation for how to do this.

Additionally please provide more detail on the functions:

- Cy_CTB_OpampGetOffset
- Cy_CTB_OpampGetSlope
- Cy_CTB_OpampSetOffset
- Cy_CTB_OpampSetSlope

And these functions that manipulate the registers:

- CTBM_OA1_OFFSET_TRIM
- CTBM_OA1_SLOPE_OFFSET_TRIM

The register locations appear to be 6-bit numbers with the MSB being a direction bit.
It isn’t clear how the direction bit is being used, i.e. is it a sign bit or something else.
Any examples related to this would be helpful.

P.S. I found partial description of the registers, “CTBM0_OA0_OFFSET_TRIM”, in the PSoC 6 Registers TRM. Similar descriptions are in the Architecture TRM.
Both TRMs (Technical Reference Manuals) are located under the “PSoC 6 Documentation” section @ https://www.infineon.com/cms/en/product/microcontroller/32-bit-psoc-arm-cortex-microcontroller/psoc-...
