Function
7
TSEQ0
R/W
Endpoint0 Data Sequence Bit. (0=DATA0, 1=DATA1)
This bit determines which type of data packet (DATA0 or DATA1) will be
sent during the next IN transaction. Toggling of this bit must be controlled
by software. RESET clears this bit
6
STALL0
R/W
Endpoint0 Force Stall Bit.
This bit causes Endpoint 0 to return a STALL handshake when polled by
either an IN or OUT token by the USB Host Controller. The USB
hardware clears this bit when a SETUP token is received. RESET clears
this bit.
5
TX0E
R/W
Endpoint0 Transmit Enable.
This bit enables a transmit to occur when the USB Host Controller sends
an IN token to Endpoint 0. Software should set this bit when data is ready
to be transmitted. It must be cleared by software when no more Endpoint
0 data needs to be transmitted. If this bit is '0' or the TXD0F is set, the
USB will respond with a NAK handshake to any Endpoint 0 IN tokens.
RESET clears this bit.
4
RX0E
R/W
Endpoint0 receive enable.
This bit enables a receive to occur when the USB Host Controller sends
an OUT token to Endpoint 0. Software should set this bit when data is
ready to be received. It must be cleared by software when data cannot be
received. If this bit is '0' or the RXD0F is set, the USB will respond with a
NAK handshake to any Endpoint 0 OUT tokens. RESET clears this bit.
