Table 19-1. USB Register Mode Encoding
Mode
This lists the mnemonic given to the different modes that can be set in the Endpoint Mode Register by writing to the lower nibble
(bits 0..3). The bit settings for different modes are covered in the column marked “Mode Bits”. The Status IN and Status OUT
represent the Status stage in the IN or OUT transfer involving the control endpoint.
Mode Bits
These column lists the encoding for different modes by setting Bits[3..0] of the Endpoint Mode register. This modes represents
how the SIE responds to different tokens sent by the host to an endpoint. For instance, if the mode bits are set to “0001” (NAK
IN/OUT), the SIE will respond with an
Refer to section 13.0 for more information on the SIE functioning
SETUP, IN and OUT
These columns shows the SIE’s response to the host on receiving a SETUP, IN and OUT token depending on the mode set in
the Endpoint Mode Register.
A “Check” on the OUT token column, implies that on receiving an OUT token the SIE checks to see whether the OUT packet is
of zero length and has a Data Toggle (DTOG) set to ‘1.’ If the DTOG bit is set and the received OUT Packet has zero length, the
OUT is ACKed to complete the transaction. If either of this condition is not met the SIE will respond with a STALLL or just ignore
the transaction.
A “TX Count” entry in the IN column implies that the SIE transmit the number of bytes specified in the Byte Count (bits 3..0 of the
Endpoint Count Register) to the host in response to the IN token received.
A “TX0 Byte” entry in the IN column implies that the SIE transmit a zero length byte packet in response to the IN token received
from the host.
