Programmable Registers
Address:
Re-
6.5.100 APBH DMA Channel 13 Next Command Address Register
The APBH DMA Channel 13 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.
APBH DMA Channel 13 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 13 semaphore to start processing. This register points to the next command
structure to be executed when the current command is completed.
Address:
Re-
6.5.101 APBH DMA Channel 13 Command Register
The APBH DMA Channel 13 command register specifies the cycle to perform for the current
command chain item.
