Programmable Registers
Address:
Re-
7.5.21 APBX DMA Channel 2 Next Command Address Register
The APBX DMA Channel 2 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 2 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 0 semaphore to start processing. This register points to the next command structure
to be executed when the current command is completed.
Address:
Re-
7.5.22 APBX DMA Channel 2 Command Register (HW_APBX_CH2_CMD)
The APBX DMA Channel 2 command register specifies the cycle to perform for the current
command chain item.
