USB INTERFACE (Cont’d)
Bits 1:0 = STAT_RX [1:0] Status bits, for reception
transfers.
These bits contain the information about the end-
point status, as listed below:
Table 21. Reception Status Encoding
These bits are written by software. Hardware sets
the STAT_RX and STAT_TX bits to NAK when a
correct transfer has occurred (CTR=1) addressed
to this endpoint, so the software has the time to ex-
amine the received data before acknowledging a
new transaction.
Notes:
If a SETUP is received while the status is other
than DISABLED, it is acknowledged and the two
directional status bits are set to NAK by hardware.
When a STALL is answered by the USB device,
the two directional status bits are set to STALL by
hardware.

DISABLED: no function can be
executed on this endpoint and
messages related to this end-
point are ignored.
STALL: the endpoint is stalled
and all reception requests re-
sult in a STALL handshake.
NAK: the endpoint is NAKed
and all reception requests re-
sult in a NAK handshake.
VALID: this endpoint is ena-
bled (if an address match oc-
curs, the USB interface
handles the transaction).

This register is used for controlling Endpoint 1 re-
ception. Bits 2:0 are also reset by a USB reset, ei-
ther received from the USB or forced through the
FRES bit in the CTLR register.
Bits 7:4 Reserved, forced by hardware to 0.
Bit 3 = CTR_RX Correct Reception Transfer.
This bit is set by hardware when a correct transfer
operation is performed in reception. This bit must
be cleared after the corresponding interrupt has
been serviced.
Bit 2 = DTOG_RX Data Toggle, for reception
transfers.
It contains the expected value of the toggle bit
(0=DATA0, 1=DATA1) for the next data packet.
The receiver toggles DTOG_RX only if it receives
a correct data packet and the packet’s data PID
matches the receiver sequence bit.
Bits 1:0 = STAT_RX [1:0] Status bits, for reception
transfers.
These bits contain the information about the end-
point status, as listed below:
Table 22. Reception Status Encoding:
These bits are written by software, but hardware
sets the STAT_RX bits to NAK when a correct
transfer has occurred (CTR=1) addressed to this
endpoint, so the software has the time to examine
the received data before acknowledging a new
transaction.

DISABLED: reception trans-

STALL: the endpoint is stalled

NAK: the endpoint is naked
and all reception requests re-

VALID: this endpoint is ena-
