DMA Configuration register (R/W: F1H/F0H)
This command defines the DMA configuration of the ISP1183 and enables or
disables DMA transfers. The command accesses the DMA Configuration register,
which consists of 2 bytes. The bit allocation is given in
Table 32
. A bus reset will clear
bit DMAEN (DMA disabled), all other bits remain unchanged.
Code (hex): F0/F1 —
write or read DMA Configuration
Transaction —
write or read 2 bytes

Unchanged by a bus reset.

Description
CNTREN
Logic 1 enables the generation of an EOT condition, when the
DMA Counter register reaches zero. Bus reset value:
unchanged.
SHORTP
Logic 1 enables the short or empty packet mode. When
receiving (OUT endpoint) a short or empty packet, an EOT
condition is generated. When transmitting (IN endpoint), this bit
should be cleared. Bus reset value: unchanged.
