14.1.7
Write/Read DMA Counter
This command accesses the DMA Counter Register. The bit allocation is given in
Table 87
. Writing to the register sets the number of bytes for a DMA transfer. Reading
the register returns the number of remaining bytes in the current transfer. A bus reset
will not change the programmed bit values.
The internal DMA counter is automatically reloaded from the DMA Counter Register
when DMA is re-enabled (DMAEN = 1). See
Section 14.1.6
for more details.
Code (Hex): F2/F3 —
write/read DMA Counter Register
Transaction —
write/read 1 word
14.1.8
Reset Device
This command resets the ISP1161 DC in the same way as an external hardware
reset via input RESET. All registers are initialized to their ‘reset’ values.
Code (Hex): F6 —
reset the device
Transaction —
none
14.2 Data flow commands
Data flow commands are used to manage the data transmission between the USB
endpoints and the system microprocessor. Much of the data flow is initiated via an
interrupt to the microprocessor. The data flow commands are used to access the
endpoints and determine whether the endpoint FIFOs contain valid data.
Remark:
The IN buffer of an endpoint contains input data
for
the host, the OUT buffer
receives output data
from
the host.
