Figure 6
:
A
: indicates the point at which the USB bus enters the idle state.
B
: indicates resume condition, which can be a 20 ms K-state on the USB bus, a
HIGH level on pin WAKEUP, or a LOW level on pin CS.
C
: indicates remote wake-up. The ISP1181B will drive a K-state on the USB bus
for 10 ms after pin WAKEUP goes HIGH or pin CS goes LOW.
D
: after detecting the suspend interrupt, set and clear bit GOSUSP in the Mode
register.

Powered-off application
Figure 7
shows a typical bus-powered modem application using the ISP1181B. The
SUSPEND output switches off power to the microcontroller and other external circuits
during the suspend state. The ISP1181B is woken up through the USB bus (global
resume) or by the ring detection circuit on the telephone line.
