DMA Controller Module Programming Model
DSR[DONE], shown in Figure 12-9, is set when the block transfer is complete.
When a transfer sequence is initiated and BCRn[BCR] is not divisible by 16, 4, or 2 when
the DMA is configured for line, longword, or word transfers, respectively, DSRn[CE] is set
and no transfer occurs. See Section 12.4.5, “DMA Status Registers (DSR0–DSR3).”
12.4.4 DMA Control Registers (DCR0–DCR3)
DCRn, Figure 12-8, is used for configuring the DMA controller module. Note that
DCR[AT] is available only if BCR24BIT = 1.
Table 12-3 describes DCR fields.

Interrupt on completion of transfer. Determines whether an interrupt is generated by completing a
transfer or by the occurrence of an error condition.
0 No interrupt is generated.
1 Internal interrupt signal is enabled.
Enable external request. Care should be taken because a collision can occur between the START
bit and DREQ when EEXT = 1.
0 External request is ignored.
1 Enables external request to initiate transfer. Internal request is always enabled. It is initiated by
writing a 1 to the START bit.
