Hello,

The p_context parameter is a void pointer (points to the address of variables) to an object used for differentiating different transfers, for example it is used in twi_mngt library. The TWI mgmt library can schedule transfers with different configs, the library will re-init the driver if the next transfer uses a different config than the previous.

p_context object provided in init function will be passed to the event handler.
