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 register
• 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.
DMACS0 contains the DMA RAM and SFR write colli-
sion flags, XWCOLx and PWCOLx, respectively.
DMACS1 indicates DMA channel and Ping-Pong mode
status.

DMAC Registers
The
DMAxCNT are all conventional read/write registers.
Reads of DMAxSTA or DMAxSTB reads the contents
of the DMA RAM Address register. Writes to DMAx-
STA or DMAxSTB write to the registers. This allows
the user to determine the DMA buffer pointer value
(address) at any time.
The interrupt flags (DMAxIF) are located in an IFSx
register in the interrupt controller. The corresponding
interrupt enable control bits (DMAxIE) are located in
an IECx register in the interrupt controller, and the cor-
responding interrupt priority control bits (DMAxIP) are
located in an IPCx register in the interrupt controller.
