The Peripheral Controller in the ISP1362 will remain in the suspend state for at least 5 ms,
before responding to external wake-up events, such as global resume, bus traffic, CS
active or LOW pulse on the D_SUSPEND/D_WAKEUP pin.

resume operations.
In
A — indicates the point at which the USB bus goes to the idle state.
B — after detecting the suspend interrupt, set and clear the GOSUSP bit in the Mode
register.
C — indicates resume condition, which can be a resume signal from the host, a LOW
pulse on the D_SUSPEND/D_WAKEUP pin, or a LOW pulse on the CS pin.
D — indicates remote wake-up. The ISP1362 will drive a K-state on the USB bus for
10 ms after the D_SUSPEND/D_WAKEUP pin goes LOW or the CS pin goes LOW.
Wake-up from the suspend state is initiated either by the USB host or by the application:
The steps of a wake-up sequence are as follows:
•
•
Figure
USB host: drives a K-state on the USB bus (global resume).
Application: remote wake-up using a LOW pulse on pin D_SUSPEND/D_WAKEUP or
a LOW pulse on pin CS (if enabled using bit WKUPCS of the
DcHardwareConfiguration register).
