APBH DMA Channel 11 is controlled by a variable sized command structure. Software
loads this register with the address of the first command structure to process and increments
the Channel 11 semaphore to start processing. This register points to the next command
structure to be executed when the current command is completed.
Address:
Re-
6.5.87 APBH DMA Channel 11 Command Register
The APBH DMA Channel 11 command register specifies the cycle to perform for the current
command chain item.
The command register controls the overall operation of each DMA command for this channel.
It includes the number of bytes to transfer to or from the device, the number of APB PIO
command words included with this command structure, whether to interrupt at command
completion, whether to chain an additional command to the end of this one and whether
this transfer is a read or write DMA transfer.
