26.4.4.1 i2c_s_async_init

Initialize asynchronous I2C slave interface.

int32_t i2c_s_async_init(
    struct i2c_s_async_descriptor *const descr,
    void *const hw,
    uint8_t *const rx_buffer,
    const uint16_t rx_buffer_length
)

This function initializes the given I2C descriptor to be used as asynchronous I2C slave interface descriptor. It checks if the given hardware is not initialized and if it is permitted to be initialized.
