7.1
Each DMAC Channel x (x = 0, 1, 2, 3, 4, 5, 6 or 7)
contains the following registers:
• A 16-bit DMA Channel Control register
• A 16-bit DMA Channel IRQ Select register
• A 16-bit DMA RAM Primary Start Address Offset
• A 16-bit DMA RAM Secondary Start Address
• A 16-bit DMA Peripheral Address register
• A 10-bit DMA Transfer Count register (DMAxCNT)
An additional pair of status registers, DMACS0 and
DMACS1, are common to all DMAC channels.
