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 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 status register, DMACS, is common to all
DMAC channels. It contains the DMA RAM and SFR
write
respectively.
The
DMAxCNT are all conventional read/write registers.
Reads of DMAxSTA or DMAxSTB will read the con-
tents of the DMA RAM Address register. Writes to
DMAxSTA 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.

7.2
Each DMA channel has its own status and control reg-
ister (DMAxCON) that is used to configure the channel
to support the following operating modes:
• Word or byte size data transfers
• Peripheral to DMA RAM or DMA RAM to
• Post-increment or static DMA RAM address
• One-shot or continuous block transfers
• Auto-switch between two start addresses after
• Force a single DMA transfer (Manual mode)
Each DMA channel can be independently configured
to:
• Select from one of 19 DMA request sources
• Manually enable or disable the DMA channel
• Interrupt the CPU when the transfer is half or fully
DMA channel interrupts are routed to the interrupt con-
troller module and enabled through associated enable
flags.
The channel DMA RAM and peripheral write collision
Faults are combined into a single DMAC error trap
(Level 10) and are not maskable. Each channel has
DMA RAM write collision (XWCOLx) and peripheral
write collision (PWCOLx) status bits in the DMAC Sta-
tus register (DMACS) to allow the DMAC error trap
handler to determine the source of the Fault condition.
