Powered-off application:
application using the ISP1161A1. The SUSPEND output switches off power to the
microcontroller and other external circuits during the suspend state. The ISP1161A1
DC is woken up through the USB bus (global resume) or by the ring detection circuit
on the telephone line.

Figure
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 D_WAKEUP, or a LOW level on pin CS.
C: indicates remote wake-up. The ISP1161A1 will drive a K-state on the USB bus
for 10 ms after pin D_WAKEUP goes HIGH or pin CS goes LOW.
D: after detecting the suspend interrupt, set and clear bit GOSUSP in the DcMode
register.
