No Automatic Generation of SYNC or EOP Packets
This functionality is considered optional in the ULPI
specification, but is supported by the FUSB2805 and
allows for the link to turn off the automatic generation of
SYNC and EOP packets. This is only pertinent to HS
packet data. It is provided for backward compatibility for
the controllers that include SYNC and EOP bytes in the
data
payload
when
transmitting
packets.
The
FUSB2805 does not automatically generate SYNC and
EOP when OPMODE[1:0]=11b. The FUSB2805 NRZI
encodes the data and performs bit stuffing. The link
must always send packets using the TXCMD(NOPID)
packet type. The FUSB2805 does not provide bit
stuffing on an individual byte basis, but automatically
turns off bit stuffing for EOP when STP is asserted with
data set to FEh. If data is set to 00h when STP is
asserted, the FUSB2805 does not transmit an EOP.
The FUSB2805 also detects if the PID byte is A5h
(indicating SOF) and automatically sends a long EOP
when STP is asserted. To transmit chirp and resume
signaling, the link sets OPMODE[1:0]=10b.
Figure 19 shows USB packets without automatic SYNC
and EOP generation.
Please refer to ULPI specification, section 3.8.5.6 for
details on no SYNC and EOP generation functionality.

OTG Operations
The FUSB2805 provides full support for OTG Rev. 1.3
compliance. The supporting functional blocks for dual-
role devices include:
Voltage comparators (for VBUS-valid, session-end,
and session-valid signaling)
DP and DM pull-up and pull-down resistors
compliant to the USB2.0 resistor ECN
ID detection for micro-A or micro-B plug insertion
VBUS charge and discharge resistors
VBUS Comparators
The FUSB2805 combines the A-device and B-device
session valid signals into VSESS_VLD due to overlapping
thresholds that allow for such combination.
The VA_VBUS_VLD threshold allows for the A-device to
determine if it is capable of outputting a valid voltage on
VBUS. For the FUSB2805, the VBUS source voltage is
external to the device when an A-device, so the
ExtVBUSIndicator signal must be utilized.
These comparators are controlled, and determine when
RXCMDs are sent, by interaction with the INTF_CTRL,
OTG_CTRL, USB_INTR_R, USB_INTR_F, USB_INTR_
STAT, and USB_INTR_L registers.
Table 13 defines use of the UseExternalVbusIndicator,
IndicatorPassThru, and IndicatorComplement register
bits to control the use of the ExternalVbusIndicator input
pin and the internal VBUS-valid comparator output to
generate the VA_VBUS_VLD indicator for encoding in
the RXCMD data byte.
Figure 20 shows a graphical representation of the
RXCMD VBUS-valid.
