Modules

• ch_al1_ctrl
  DMA Channel 0 Control and Status
• ch_al1_read_addr
  Alias for channel 0 READ_ADDR register
• ch_al1_trans_count_trig
  Alias for channel 0 TRANS_COUNT register
  This is a trigger register (0xc). Writing a nonzero value will
  reload the channel counter and start the channel.
• ch_al1_write_addr
  Alias for channel 0 WRITE_ADDR register
• ch_al2_ctrl
  DMA Channel 0 Control and Status
• ch_al2_read_addr
  Alias for channel 0 READ_ADDR register
• ch_al2_trans_count
  Alias for channel 0 TRANS_COUNT register
• ch_al2_write_addr_trig
  Alias for channel 0 WRITE_ADDR register
  This is a trigger register (0xc). Writing a nonzero value will
  reload the channel counter and start the channel.
• ch_al3_ctrl
  DMA Channel 0 Control and Status
• ch_al3_read_addr_trig
  Alias for channel 0 READ_ADDR register
  This is a trigger register (0xc). Writing a nonzero value will
  reload the channel counter and start the channel.
• ch_al3_trans_count
  Alias for channel 0 TRANS_COUNT register
• ch_al3_write_addr
  Alias for channel 0 WRITE_ADDR register
• ch_ctrl_trig
  DMA Channel 0 Control and Status
• ch_read_addr
  DMA Channel 0 Read Address pointer
  This register updates automatically each time a read completes. The current value is the next address to be read by this channel.
• ch_trans_count
  DMA Channel 0 Transfer Count
  Program the number of bus transfers a channel will perform before halting. Note that, if transfers are larger than one byte in size, this is not equal to the number of bytes transferred (see CTRL_DATA_SIZE).
• ch_write_addr
  DMA Channel 0 Write Address pointer
  This register updates automatically each time a write completes. The current value is the next address to be written by this channel.
