ISP1362
Single-chip USB OTG controller
Philips Semiconductors
1. The internal oscillator and the PLL multiplier are re-enabled. When stabilized, the
clock signals are routed to all internal circuits of the DC in the ISP1362.
2. The D_SUSPEND/D_WAKEUP pin goes LOW, and the RESUME bit of the
DcInterrupt register is set. This will generate an interrupt if bit IERESUME of the
DcInterruptEnable register is set.
3. 5 ms after starting the wake-up sequence, the DC in the ISP1362 resumes its
normal functionality (this could be set to 100 µs by setting pin TEST0 to HIGH).
4. In case of a remote wake-up, the DC in the ISP1362 drives a K-state on the USB
bus for 10 ms.
5. The application restores itself and other system components to normal operating
mode.
6. After wake-up, the internal registers of the DC in the ISP1362 are read and
write-protected to prevent corruption by inadvertent writing during power-up of
external components. The firmware must send an Unlock Device command to
the DC in the ISP1362 to restore its full functionality.
