8.4 Remote wake-up
After entering the suspend state with DEV_CLK_EN and AHB_CLK_EN cleared, the
DEV_CLK_ON and AHB_CLK_ON will be cleared when the corresponding clock turns off.
When both bits are zero, USB_NEED_CLK will be low, indicating that the chip can be put
into Power-down mode by writing to the PCON register. The status of USB_NEED_CLK
can be read from the USBIntSt register.
Any bus activity in the suspend state will cause the USB_NEED_CLK signal to be
asserted. When the USB is configured to be a wakeup source from power-down
(USBWAKE bit set in the INTWAKE register), the assertion of USB_NEED_CLK causes
the chip to wake up from Power-down mode.
The USB device controller supports software initiated remote wake-up. Remote wake-up
involves resume signaling on the USB bus initiated from the device. This is done by
clearing the SUS bit in the SIE Set Device Status register. Before writing into the register,
all the clocks to the device controller have to be enabled using the USBClkCtrl register.
