In the DACK-only mode, the ISP1161A1’s DC uses the DACK2 signal as a data
strobe. Input signals RD and WR are ignored. This mode is used in CPU systems that
have a single address space for memory and I/O access. Such systems have no
separate MEMW and MEMR signals: the RD and WR signals are also used as
memory data strobes.
12.4 End-Of-Transfer conditions
12.4.1
Bulk endpoints
A DMA transfer to/from a bulk endpoint can be terminated by any of the following
conditions (bit names refer to the DcDMAConguration register, see Table 86):
An external End-Of-Transfer signal occurs on input EOT
The DMA transfer completes as programmed in the DcDMACounter register
(CNTREN = 1)
A short packet is received on an enabled OUT endpoint (SHORTP = 1)
DMA operation is disabled by clearing bit DMAEN.
External EOT: When reading from an OUT endpoint, an external EOT will stop the
DMA operation and clear any remaining data in the current FIFO. For a double-
buffered endpoint the other (inactive) buffer is not affected.
When writing to an IN endpoint, an EOT will stop the DMA operation and the data
packet in the FIFO (even if it is smaller than the maximum packet size) will be sent to
the USB host at the next IN token.
