Modes of Operation
ULPI Modes
The ULPI bus can be programmed to operate in four
different modes and a power-down mode. Each mode
re-configures the signals on the data bus. Setting more
than one mode leads to undefined behavior.
Synchronous Mode
This is the default mode. On power-up and when CLOCK
is stable, the FUSB2805 enters synchronous mode.
In
synchronous
mode,
the
link
controller
must
synchronize all ULPI signals to CLOCK, meeting the
setup
and
hold
times
defined
in
the
Dynamic
Characteristics tables.
This mode is used by the link controller to perform the
following tasks:
Detect high-speed handshake (chirp)
Transmit and receive USB packets
Read and write to registers
Receive USB status updates (RX CMDs) from
FUSB2805
Please refer to section 3.8 of the ULP Rev. 1.1
specification for further details.
Low-Power Mode
When the USB is idle, the link controller can place the
FUSB2805 into low-power mode (also known as
“suspend” mode). To enter low-power mode, the link
controller clears the SUSPENDM bit in the function
control (FUNC_CTRL) register to 0b.
During low-power mode, the FUSB2805 provides line
state and interrupt information on the data bus for the
link controller to monitor basic USB states and draws
less than 200 A from the VCC supply.
In addition, during low-power mode, the clock on CLKIN
may be stopped; but it must be restarted before
asserting STP to exit low-power mode.
Once in low-power mode, the FUSB2805 must remain
in low-power mode for a minimum of 120 clock cycles
(or 2 s). After the 2 s delay, low-power mode may be
exited by asserting the STP signal. The FUSB2805 then
issues an RXCMD to the link if a change was detected
in any interrupt source and the change still exists. An
RXCMD may not be sent if the interrupt condition is
removed before exiting.
In low-power mode, the data bus assignments are
changed to those described in Table 1.

Entering Low-Power Mode
The link sets SuspendM=0b (in Function Control
Register) to place the FUSB2805 into low-power
mode. The CLOCK may be stopped a minimum of
five (5) cycles after the FUSB2805 accepts the
register write data as described in Figure 6. When
entering low-power mode, the FUSB2805 asserts DIR
and holds NXT LOW. There is one cycle of data bus
turnaround provided after the assertion of DIR, during
which the value of D[7:0] is not valid. Upon
completion of the turnaround cycle the FUSB2805
begins driving the signals as described in Table 1.
