Remark:
There is no protection against writing or reading past a buffer’s boundary,
against writing into an OUT buffer or reading from an IN buffer. Any of these actions
could cause an incorrect operation. Data residing in an OUT buffer are only
meaningful after a successful transaction. Exception: during DMA access of a
double-buffered endpoint, the buffer pointer automatically points to the secondary
buffer after reaching the end of the primary buffer.
12.2.2
Write/Read Endpoint Status
This command is used to read the status of the endpoint FIFO or stall the endpoint by
writing. The command accesses the Endpoint Status Register, the bit allocation of
which is shown in
Table 33
.
A stalled control endpoint is automatically unstalled when it receives a SETUP token,
regardless of the packet content. If the endpoint should stay in its stalled state, the
microcontroller can re-stall it with the Write Endpoint Status command.
