High-Speed Suspend and Resume
The sequence of events for a host and HS peripheral
using FUSB2805 is described below and shown in
Sequence of events:
1.
HS Traffic
– Initially both the host and peripheral
are idle. The host has its 15
kΩ pull-down resistors
enabled
(DP_PULLDOWN=DM_PULLDOWN=1b)
and
the
45
Ω
terminations
enabled
(TERMSELECT=0b). The peripheral has its 45
Ω
terminations enabled (TERMSELECT=0b).
2.
FS Suspend - If the peripheral detects no bus
activity for 3 ms, it enters the suspend state. The
peripheral link places the FUSB2805 into FS mode
(XCVRSELECT[1:0]=01b),
removes
the
45
Ω
terminations,
and
enables
the
1.5
kΩ pull-up
resistor on DP (TERMSELECT=1b). The peripheral
link then 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 also changes
the
FUSB2805
to
FS
mode
(XCVRSELECT[1:0]=01b),
removes
the
45
Ω
terminations (TERMSELECT=1b), and 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 full-speed K-state for at least 20 ms. The
peripheral link detects the resume-K (10b) on
LINESTATE and asserts STP to wake FUSB2805.
4.
HS
Traffic
–
the
host
link
sets
HS
(XCVRSELECT[1:0]=00b) and enables its 45
Ω
terminations (TERMSELECT=0b). The peripheral
link detects SE0 on LINESTATE, sets HS mode
(XCVRSELECT[1:0]=00b), and enables its 45
Ω
terminations (TERMSELECT=0b). The host link
sets OPMODE[1:0]=00b for normal HS operation.

HS Suspend and Resume Timing
Note:
19. 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.
