4.13.3 Entering Sleep Mode

This section applies to devices of revision C2 and earlier.

After wake-up has been configured, the host controller may command the device to enter the SLEEP state. This is done by writing a ‘1’ to the Sleep Enable (SLPEN) bit in the Sleep Control 0 (SLPCTL0) register. Alternatively the device may also be configured to enter SLEEP automatically upon expiration of an inactivity watchdog as detailed below.
