Expand description

@brief Group of I2C master callbacks, can be used to get status during transaction or doing other small things. But take care potential concurrency issues. @note The callbacks are all running under ISR context @note When CONFIG_I2C_ISR_IRAM_SAFE is enabled, the callback itself and functions called by it should be placed in IRAM. The variables used in the function should be in the SRAM as well.
