OVERVIEW
The target MCU features an on-board USB On-the-Go (OTG) physical layer (Phy). The OTG
Phy may be configured for either Host or Peripheral mode depending on the target application.
The OTG protocol also allows mode switching under software control. The miniAB (MAB) con-
nector at J2 provides access to the OTG Phy. The USB connection may be configured for ei-
ther standard USB bus operation or OTG USB bus operation.
The MAB USB port connector at J2 should not be confused with the integrated USB BDM cir-
cuit connector at J301. These are 2 separate circuits and do not interact in any way. The
MAB USB port provides access to the integrated USB Phy on the target MCU. The USB BDM
connector allows the user to communicate with the target MCU using either CodeWarrior or
P&E Microcomputer Systems debugger tools and a USB2.0 cable. Remember the distinction
between the 2 USB connectors when reading this document.
The M52210DEMO provides two separate voltage rails for proper operation. The regulator at
VR1 energizes the +3.3V rail for use by the target MCU and on-board logic. The regulator at
VR2 energizes the +5Vrail for use by the OTG USB port.
