DMAx I/O Address Register
1 = DMAx, after the End Address data is transferred, reloads the original Start
DDIR—DMAx Data Transfer Direction
0 = Register File → on-chip peripheral control register.
1 = on-chip peripheral control register → Register File.
IRQEN—DMAx Interrupt Enable
0 = DMAx does not generate any interrupts.
1 = DMAx generates an interrupt when the End Address data is transferred.
WSEL—Word Select
0 = DMAx transfers a single byte per request.
1 = DMAx transfers a two-byte word per request. The address for the on-chip
RSS—Request Trigger Source Select
The Request Trigger Source Select field determines the peripheral that can initiate a DMA
transfer. The corresponding interrupts do not need to be enabled within the Interrupt Con-
troller to initiate a DMA transfer. However, if the Request Trigger Source can enable or
disable the interrupt request sent to the Interrupt Controller, the interrupt request must be
enabled within the Request Trigger Source block.
000 = Timer 0.
001 = Timer 1.
010 = Timer 2.
011 = Timer 3.
100 = DMA0 Control register: UART0 Received Data register contains valid data.
101 = DMA0 Control register: UART1 Received Data register contains valid data. DMA1
Control register: UART1 Transmit Data register empty.
110 = DMA0 Control register: I
111 = Reserved.
The DMAx I/O Address register
address for data transfer. The full 12-bit Register File address is given by {FH,
Address and continues operating.
peripheral control register must be an even address.
DMA1 Control register: UART0 Transmit Data register empty.
Transmitter Interrupt register empty.
