SPI Port
SPI signaling connects directly between connector J1 and the MCU. Refer to the MCF522235

USB OTG
The M52210DEMO features an integrated USB On-the Go (OTG) physical layer (Phy) inter-
face. The OTG Phy connects to an MAB connector at J2. Two option headers at DPPD and
DMPD provide pull-down configuration for host mode if needed. Installing or removing both
jumpers manually controls pull-down configuration. Pull-up configuration for device mode is
integral to the MCF52210 MCU.
A high-side switch at U2 provides power to the USB bus when the board is configured for host
mode. The ILIM option header sets the output current limit. See the USB OTG Power section
above for further details.
Refer to the MCF52223 RM for additional information on using the OTG Phy. Also refer to the
USB2.0 Specification and the On-the-Go Supplement to the USB2.0 Specification for addi-
tional information. The USB2.0 Specification and the OTG Supplement can be downloaded
from the USB Implementers Forum (USB-IF) at www.usb.org. These documents are also
available on the Axiom Manufacturing Support CD.
ACCELEROMETER
The M52210DEMO applies an MMA7260Q, 3-axis accelerometer for tilt and motion-sense ap-
plications. The accelerometer supports 4 user selectable sensitivities - 1.5g / 2g / 4g / 6g. The
SLEEP* input allows the device to be placed in a low-power mode. Separate (X/Y/Z) axis
readings are routed to the MCU
An option header at ACC_EN allows the user to disconnect the accelerometer if necessary. In
default configurations, this option header is not installed and a cut-trace completes the signal
path. To disconnect the accelerometer, simply open the cut-trace and install a 1x3 pin-header
at ACC_EN. Install a shunt on each signal to reconnect the accelerometer. The table below
shows the signal connections to the MCU.
