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
Read Endpoint Status
This command is used to read the status of an endpoint FIFO. The command
accesses the Endpoint Status Register, the bit allocation of which is shown in
Table 31
. Reading the Endpoint Status Register will clear the interrupt bit set for the
corresponding endpoint in the Interrupt Register (see
Table 48
).
All bits of the Endpoint Status Register are read-only. Bit EPSTAL is controlled by the
Stall/Unstall commands and by the reception of a SETUP token (see
Section 12.2.3
).
Code (Hex): 50 to 5F —
read (control OUT, control IN, endpoint 1 to 14)
