Table 53
Register SELECT_EP0_OUT (address: 0x00H)
Detailed description of the optional read (1 byte) following command 0x00H; note 1
Notes
1.
The SELECT_EPX_XX command selects the corresponding EP buffer. It can be followed optionally by a data read,
which provides the EP status to the microcontroller (see the detailed description above). Whatever the EP (from 0
to 3) or its direction, the sequence is the same. Note that isochronous EP cannot be selected in this way.
BUFFER_STATUS: in case of an IN endpoint; this bit is set by the VALIDATE_BUFFER command.

SENT_NAK:
a NAK is not sent (by default)
a NAK is sent by the device
PACKET_OVERWRITTEN:
not overwritten (by default)
the previously received packet was overwritten by a setup packet
SETUP_PACKET: give the status of the last received packet
not a setup packet (by default)
last received packet for the selected EP was a setup packet
STALL_PACKET: give the status of the selected EP
not stall (by default)
stall
BUFFER_STATUS: give the EP buffer status; note 2; this bit is cleared by
executing the SET_BUFFER_FE command
buffer not full (by default)
buffer of the selected EP is full
