RE: how to switch peripheral use at runtime

Hi,

You cannot use several peripheral instances that share the same IDs/base addresses at the same time. Here is the table of which IDs/base address the different peripheral instances use. Here you can see that e.g. TWIS0 and SPIS0 have the same ID, and cannot be used together.

But, you can use peripheral resource sharing(PERIPHERAL_RESOURCE_SHARING_ENABLED). This enables you to first use e.g. TWIS0, then you have to uninitialized it, and then you can use SPIS0.
