Use
This is an internal call for OS use only and should not be used by user software.
Returns the device number for the requested IIC bus.
This call is not meaningful if bit 4 of the HAL_IICType flags word is not set. The OS will claim the interrupt and call HAL_IICMonitorTransfer each time it occurs.
