Write/Read DMA Configuration
This command defines the DMA configuration of ISP1161’s DC and enables/disables
DMA transfers. The command accesses the DMA Configuration Register, which
consists of 2 bytes. The bit allocation is given in
Table 85
. A bus reset will clear bit
DMAEN (DMA disabled), all other bits remain unchanged.

Description
A logic 1 enables the generation of an EOT condition, when the
DMA Counter Register reaches zero. Bus reset value:
unchanged.
A logic 1 enables short/empty packet mode. When receiving
(OUT endpoint) a short/empty packet an EOT condition is
generated. When transmitting (IN endpoint) this bit should be
cleared. Bus reset value: unchanged.
reserved
Indicates the destination endpoint for DMA, see
Table 10
.
Writing a logic 1 enables DMA transfer, a logic 0 forces the end
of an ongoing DMA transfer and generates an EOT interrupt.
Reading this bit indicates whether DMA is enabled (0 = DMA
stopped, 1 = DMA enabled). This bit is cleared by a bus reset.
reserved
Selects the DMA burst length:
00 —
single-cycle mode (1 byte)
01 —
burst mode (4 bytes)
10 —
burst mode (8 bytes)
11 —
burst mode (16 bytes).
Bus reset value: unchanged.
