Table 124. Endpoint buffer memory organization
Table 125. Example of endpoint buffer memory access
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 can
cause an incorrect operation. Data residing in an OUT buffer is only meaningful after a
successful transaction. Exception: during the DMA access of a double-buffered endpoint,
the buffer pointer automatically points to the secondary buffer after reaching the end of the
primary buffer.
This command is used to read the status of an endpoint buffer memory. The command
accesses the DcEndpointStatus register, the bit allocation of which is shown in
Reading the DcEndpointStatus register will clear the interrupt bit set for the corresponding
endpoint in the DcInterrupt register (see
All bits of the DcEndpointStatus register are read-only. Bit EPSTAL is controlled by the
Stall or Unstall commands and by the reception of a set-up token (see
Code (Hex): 50 to 5F — read (control OUT, control IN, endpoints 1 to 14)
