Minimum Hardware Requirements for Standalone Mode – Peripheral Only
Power Savings and Reset Description
The EZ-OTG modes and reset conditions are described in this
section.
Power Savings Mode Description
EZ-OTG has one main power savings mode, Sleep. For
detailed information on Sleep mode;
Sleep mode is used for USB applications to support USB
suspend and non USB applications as the main chip power
down mode.
In addition, EZ-OTG is capable of slowing down the CPU clock
speed through the CPU Speed register [0xC008] without
affecting other peripheral timing. Reducing the CPU clock
speed from 48 MHz to 24 MHz reduces the overall current
draw by around 8 mA while reducing it from 48 MHz to 3 MHz
reduces the overall current draw by approximately 15 mA.

Sleep
Sleep mode is the main chip power down mode and is also
used for USB suspend. Sleep mode is entered by setting the
Sleep Enable (bit 1) of the Power Control register [0xC00A].
During Sleep mode (USB Suspend) the following events and
states are true:
• GPIO pins maintain their configuration during sleep (in
• External Memory Address pins are driven low.
• XTALOUT is turned off.
• Internal PLL is turned off.
• Firmware must disable the charge pump (OTG Control
• Booster circuit is turned off.
• USB transceivers is turned off.
• CPU suspends until a programmable wakeup event.
