 These functions access the communication channels registers contained in the vci_mwmr_dma controller.
 
- === void '''_mwr_channel_init'''( unsigned int cluster_xy, unsigned int channel, unsigned int mode, unsigned long long buffer_paddr, unsigned int buffer_size, unsigned long long desc_paddr, unsigned long long lock_paddr ) ===
-This function initialises all registers defining one communication channel for a given coprocessor.
- * '''cluster_xy''' is the cluster index
- * '''channel''' is the channel index
- * '''mode''' is the requested mode (MWMR / DMA_IRQ / DMA_NO_IRQ)
- * '''buffer_paddr''' is the memory buffer physical address
- * '''buffer_size''' is the memory buffer size (bytes)
- * '''desc_paddr''' is the MWMR descriptor physical address (only used in MWMR mode)
- * '''lock_paddr''' is the MWMR lock physical address (only used in MWMR mode)
+ === void '''_mwr_set_channel_register'''( unsigned int cluster_xy ,  unsigned int channel ,  unsigned int index ,  unsigned int value ) ===
+This function set a a new value in a coprocessor register.
+ * '''cluster_xy''' : cluster coordinates.
+ * '''channel''': channel index.
+ * '''index''' : register index.
+ * '''value''' : value to be written.
 
- === void '''_mwr_channel_start'''( unsigned int cluster_xy,  unsigned int channel ) ===
-This function activates one communication channel for a given coprocessor (set a non zero value in the RUNNING channel register).
- * '''cluster_xy''' is the cluster index
- * '''channel''' is the channel index
+ === unsigned int '''_mwr_get channel_register'''( unsigned int cluster_xy , unsigned int channel,  unsigned int index) ===

+ * '''channel''': channel index.
+ * '''index''' : register index.
 
- === void '''_mwr_channel_stop'''( unsigned int cluster_xy,  unsigned int channel ) ===
-This function desactivates one communication channel for a given coprocessor (set a zero value in the RUNNING channel register).
- * '''cluster_xy''' is the cluster index
- * '''channel''' is the channel index
