11.2 Resume conditions
A wake-up from the suspend state is initiated either by the USB host or by the
application:
USB host
: drives a K-state on the USB bus (global resume)
Application
: remote wake-up through a HIGH level on input WAKEUP or a LOW
level on input CS (if enabled using bit WKUPCS in the Hardware Configuration
register). Wake-up on CS will work only if V
BUS
is present.
The steps of a wake-up sequence are as follows:
1. The internal oscillator and the PLL multiplier are re-enabled. When stabilized, the
clock signals are routed to all internal circuits of the ISP1181A.
2. The SUSPEND output is deasserted, and bit RESUME in the Interrupt register is
set. This will generate an interrupt if bit IERESUME in the Interrupt Enable
register is set.
3. Maximum 15 ms after starting the wake-up sequence, the ISP1181A resumes its
normal functionality.
4. In case of a remote wake-up, the ISP1181A drives a K-state on the USB bus for
10 ms.
5. Following the deassertion of output SUSPEND, the application restores itself and
other system components to the normal operating mode.
6. After wake-up, the internal registers of the ISP1181A are write-protected to
prevent corruption by inadvertent writing during power-up of external
components. The firmware must send an Unlock Device command to the
ISP1181A to restore its full functionality.
