Definition
Number of clock cycles a host link must wait before driving
the TXCMD for the second packet.
In high-speed, the link starts counting from the assertion of
STP for the first packet.
In full-speed, the link starts counting from the RXCMD,
indicating LINESTATE has changed from SE0 to J for the
first packet. The timing given ensures inter-packet delays of
2 bit times to 6.5 bit times.
Number of clock cycles the link must wait before driving the
TXCMD for the transmit packet.
In high-speed, the link starts counting from the end of the
receive packet; deassertion of DIR or an RXCMD, indicating
RxActive is LOW.
In full-speed or low-speed, the link starts counting from the
RXCMD, indicating LINESTATE has changed from SE0 to J
for the receive packet. The timing given ensures
inter-packet delays of 2 bit times to 6.5 bit times.
Minimum number of clock cycles between consecutive
receive packets. The link must be able to receive both
packets.
Host or peripheral transmits a packet and will time-out after
this number of clock cycles if a response is not received.
Any subsequent transmission can occur after this time.
