z
Transmit must be asserted to enable any transmissions.
z
The SIE asserts TXVLD to begin a transmission.
z
The SIE negates TXVLD to end a transmission.
z
After the SIE asserts TXVLD it can assume that the transmission has started when it
detects TXRDY asserted.
z
The SIE assumes that the UTM has consumed a data byte if TXRDY and TXVLD are
asserted.
z
The SIE must have valid packet information (PID) asserted on the Data bus
coincident with the assertion of TXVLD. Depending on the UTM implementation,
TXRDY may be asserted by the Transmit State Machine as soon as one CLK after
the assertion of TXVLD.
z
TXVLD and TXRDY are sampled on the rising edge of CLKOUT.
z
The Transmit State Machine does not automatically generate Packet ID’s (PIDs) or
