USB3370
Transfer of the RXCMD byte occurs in Synchronous Mode when the PHY has control of the bus. The ULPI Protocol
Block shown in Figure 6-1 determines when to send an RXCMD. A RXCMD will occur:
• When a linestate change occurs.
• When VBUS or ID comparators change state.
• During a USB receive when NXT is low.
• After the USB3370 deasserts DIR and STP is low during start-up
• After the USB3370 exits Low Power Mode, Serial Modes, or Carkit Mode after detecting that the Link has de-
asserted STP, and DIR is low.
When a USB Receive is occurring, RXCMD’s are sent whenever NXT = 0 and DIR = 1. During a USB Transmit, the
RXCMD’s are returned to the Link after STP is asserted.
If an RXCMD event occurs during a Hi-Speed USB transmit, the RXCMD is blocked until STP de-asserts at the end of
the transmit. The RXCMD contains the status that is current at the time the RXCMD is sent.
