Programmable Registers
7.5.83 APBX DMA Channel 11 Current Command Address Register
The APBX DMA Channel 11 current command address register points to the multiword
command that is currently being executed. Commands are threaded on the command address.
APBX DMA Channel 11 is controlled by a variable sized command structure. This register
points to the command structure currently being executed.
Address:
Re-
7.5.84 APBX DMA Channel 11 Next Command Address Register
The APBX DMA Channel 11 next command address register points to the next multiword
command to be executed. Commands are threaded on the command address. Set CHAIN
to one to process command lists.
APBX 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.
