##### How to use this driver #####
==============================================================================
[..]
The IPCC HAL driver can be used as follows:
(#) Declare a IPCC_HandleTypeDef handle structure, for example: IPCC_HandleTypeDef hipcc;
(#) Initialize the IPCC low level resources by implementing the HAL_IPCC_MspInit() API:
(##) Enable the IPCC interface clock
(##) NVIC configuration if you need to use interrupt process
(+++) Configure the IPCC interrupt priority
(+++) Enable the NVIC IPCC IRQ
(#) Initialize the IPCC registers by calling the HAL_IPCC_Init() API which trig
HAL_IPCC_MspInit().
(#) Implement the interrupt callbacks for transmission and reception to use the driver in interrupt mode
(#) Associate those callback to the corresponding channel and direction using HAL_IPCC_ConfigChannel().
This is the interrupt mode.
If no callback are configured for a given channel and direction, it is up to the user to poll the
status of the communication (polling mode).
(#) Notify the other MCU when a message is available in a chosen channel
or when a message has been retrieved from a chosen channel by calling
the HAL_IPCC_NotifyCPU() API.

##### IO operation functions #####
===============================================================================
[..] This section provides functions to allow two MCU to communicate.
(#) For a given channel (from 0 to IPCC_CHANNEL_NUMBER), for a given direction
IPCC_CHANNEL_DIR_TX or IPCC_CHANNEL_DIR_RX, you can choose to communicate
in polling mode or in interrupt mode using IPCC.
By default, the IPCC HAL driver handle the communication in polling mode.
By setting a callback for a channel/direction, this communication use
the interrupt mode.
(#) Polling mode:
(++) To transmit information, use HAL_IPCC_NotifyCPU() with
IPCC_CHANNEL_DIR_TX. To know when the other processor has handled
the notification, poll the communication using HAL_IPCC_NotifyCPU
with IPCC_CHANNEL_DIR_TX.
(++) To receive information, poll the status of the communication with
HAL_IPCC_GetChannelStatus with IPCC_CHANNEL_DIR_RX. To notify the other
processor that the information has been received, use HAL_IPCC_NotifyCPU
with IPCC_CHANNEL_DIR_RX.
(#) Interrupt mode:
(++) Configure a callback for the channel and the direction using HAL_IPCC_ConfigChannel().
This callback will be triggered under interrupt.
(++) To transmit information, use HAL_IPCC_NotifyCPU() with
IPCC_CHANNEL_DIR_TX. The callback configured with HAL_IPCC_ConfigChannel() and
IPCC_CHANNEL_DIR_TX will be triggered once the communication has been handled by the
other processor.
(++) To receive information, the callback configured with HAL_IPCC_ConfigChannel() and
IPCC_CHANNEL_DIR_RX will be triggered on reception of a communication.To notify the other
processor that the information has been received, use HAL_IPCC_NotifyCPU
with IPCC_CHANNEL_DIR_RX.
(++) HAL_IPCC_TX_IRQHandler must be added to the IPCC TX IRQHandler
(++) HAL_IPCC_RX_IRQHandler must be added to the IPCC RX IRQHandler
