[USB Endpoint x (x = 1 to 4) OUT Control Register] OUT_CSR
This register contains the information and status of the respective
OUT endpoints 1 to 4. In the endpoint 0, all bits are reserved and
cannot be used (they will all be read out as
“
0
”
). The USB FCU
sets the OUT_PKT_RDY flag to
“
1
”
after a data packet has been
received into the OUT FIFO. After reading the data packet in the
OUT FIFO, clear this flag to
“
0
”
. However, if there is still data in the
OUT FIFO, the flag cannot be cleared even by writing
“
0
”
by soft-
ware.
