Expand description

@brief Group of I2C slave callbacks (e.g. get i2c slave stretch cause). But take care of 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.
