/*******************************************************************************
* Function Name: Cy_IPC_Drv_SendMsgWord
****************************************************************************//**
*
* This function is used to send a 32-bit word message through an IPC channel.
* The function also has an associated notification field that will let the
* message notify one or multiple IPC interrupts. The IPC channel is locked and
* remains locked after the function returns. The receiver of the message should
* release the channel.
*
* \param base
* This parameter is a handle that represents the base address of the registers
* of the IPC channel.
* The parameter is generally returned from a call to the \ref
* Cy_IPC_Drv_GetIpcBaseAddress.
*
* \param notifyEventIntr
* Bit encoded list of IPC interrupt lines that are triggered by a notification.
*
* \param message
* The message word that is the data placed in the IPC data register.
*
* \return Status of the operation:
* \retval CY_IPC_DRV_SUCCESS: The send operation was successful.
* \retval CY_IPC_DRV_ERROR: The IPC channel is unavailable because it is already locked.
