| Entry | |
|---|---|
| descs | Pointer to list of iic_transfer structures |

Use
This call is a simple wrapper to IIC_OpV, an internal kernel routine which is used by SWI OS_IICOp to handle IIC transfers. As such, it allows the HAL to perform IIC transfers.
Note that it is only safe to call this function once HAL_Init has completed.
