The CPU writes a “1” to the CLR_OUT_BUF_RDY bit after a data set has been unloaded from the buffer
by the CPU (updates the OUT_BUF_STS1 & OUT_BUF_STS0 flags).
If the buffer has one more data set in it, the buffer status flags transition from 112 to 102 .
If the buffer has no more data set in it, the buffer status flags transition from 102 to 002 .
AUTO_CLR is enabled and continuous transfer mode disabled:
Single Buffer Mode:
The USB FCU updates the corresponding EPx OUT CSR’s OUT_BUF_STS1 & OUT_BUF_STS0 flags
from 002 to 112 after it has successfully received a data packet from the host.
The USB FCU updates the OUT_BUF_STS1 & OUT_BUF_STS0 flags from 112 to 002 automatically
when the data packet has been unloaded from the buffer by the CPU without the CPU writing a “1” to the
CLR_OUT_BUF_RDY bit.
Double Buffer Mode:
The USB FCU updates the corresponding EPx OUT CSR’s OUT_BUF_STS1 & OUT_BUF_STS0 flags
after it has successfully received a data packet from the host.
If the buffer has only one data packet, the buffer status flags transition from 002 to 102 .
If the buffer has two data packets, the buffer status flags transition from 102 to 112 .
The USB FCU updates the OUT_BUF_STS1 & OUT_BUF_STS0 flags automatically when a data packet
has been unloaded from the buffer by the CPU without the CPU writing a “1” to the CLR_OUT_BUF_RDY
bit.
If the buffer has one more data packet in it, the buffer status flags transition from 112 to 102 .
AUTO_CLR is enable and continuous transfer mode enabled:
Single Buffer Mode:
The USB FCU updates the corresponding EPx OUT CSR’s OUT_BUF_STS1 & OUT_BUF_STS0 flags
from 002 to 112 after it has successfully received a data set equal to its buffer size or a short packet from
the host.
The USB FCU updates the OUT_BUF_STS1 & OUT_BUF_STS0 flags from 112 to 002 automatically
when the data set has been unloaded from the buffer by the CPU without the CPU writing a “1” to the
CLR_OUT_BUF_RDY bit.

been unloaded from the buffer by the CPU without the CPU writing a “1” to the CLR_OUT_BUF_RDY bit.

If the buffer has no more data set in it, the buffer status flags transition from 102 to 002.
