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 is meaningful only
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.
13.2.2
Endpoint Status register (R: 50H–5FH)
This command reads the status of an endpoint FIFO. The command accesses the
Endpoint Status register, the bit allocation of which is shown in
Table 26
. Reading the
Endpoint Status register will clear the interrupt bit set for the corresponding endpoint
in the Interrupt register (see
Table 46
).
All bits of the Endpoint Status register are read-only. Bit EPSTAL is controlled by the
Stall or Unstall commands and by the reception of a SETUP token
(see
Section 13.2.3
).
