USB Suspend and Resume
This section describes the suspend and resume
functionality, when initiated by a host or hub, and how to
subsequently wake the downstream peripheral.
Full-Speed Suspend and Resume
The sequence of events for a host and peripheral using
FUSB2805 is described below and shown in Figure 15.
Sequence of events:
1.
FS Traffic
– Initially both the host and peripheral
are
sending
FS
traffic
over
the
USB
bus
(XCVRSELECT = 01b). The host has its 15
kΩ pull-
down
resistors
enabled
(DP_PULLDOWN
=
DM_PULLDOWN = 1b) and the 45
Ω terminations
disabled (TERMSELECT=1b). The peripheral has
the 1.5
kΩ pull-up connected to DP for full-speed.
or DM for low-speed (TERMSELECT is set to 1b).
2.
Suspend
– If the peripheral detects no bus activity
for 3 ms, it enters
“suspend” state. The peripheral
places the FUSB2805 into low-power mode by
clearing the SUSPENDM bit in the FUNC_CTRL
register, causing the FUSB2805 to draw only
suspend current. The host may or may not be
powered down.
3.
Resume K
– When the host wishes to wake the
peripheral, it sets OPMODE[1:0]=10b and transmits
a K-state for at least 20 ms. The peripheral link
detects the resume-K on LINESTATE and asserts
STP to wake the FUSB2805.
4.
EOP
– When STP is asserted, the FUSB2805 on
the host side automatically appends an EOP (End
of Packet) of two bits of SE0 at LS bit rate, followed
by one bit of J-state. The FUSB2805 on the host
side
knows
to
add
the
EOP
because
DP_PULLDOWN and DM_PULLDOWN are set to
1b for a host. After the EOP is completed, the host
link
sets
OPMODE[1:0]=00b
for
normal
FS
operation. The peripheral link detects the EOP and
resumes normal FS operation.

FS Suspend and Resume Timing (Timing Not to Scale)
Note:
18. Timing is not to scale and not all the RXCMD updates or bus turn-around cycles are necessarily shown. The bus
turn-around cycles would be included for one cycle after every assertion and de-assertion of DIR.
