Product data
Wake-up by pin CS (software wake-up):
external microprocessor issues a chip select signal through pin CS. This method of
access to the ISP1161A1 internal registers is a software wake-up.
Wake-up by USB devices:
root hub port issues a resume signal to the HC through the USB bus, switching
the HC from the USBSuspend state to the USBResume state. This will also set
bit ResumeDetected of the HcInterruptStatus register (03H to read, 83H to write).
No matter which method is used to wake up the HC from the USBSuspend state, the
corresponding interrupt bits must be enabled before the HC goes into the
USBSuspend state so that the microprocessor can receive the correct interrupt
request to wake up the HC.
