The LCD_EN option header allows module SPI signals to be used as general purpose I/O if
needed. Removing the option header shunt prevents the shift register from loading the GPIO
signal.

USB CONTROLLER
The EVB51JM128 provides an on-board USB physical layer interface (PHY) capable of Host
mode, Device mode, and On-the-Go (OTG) mode applications. A Type-A USB connector
supports Host mode connections. A miniAB connector supports OTG applications. An op-
tional 6-in-1 USB cable supports Device mode applications. The output USB signal lines
(USBP, USBN) are biased either manually or under program control.
PD_EN and USPD are used to configure the USB lines manually. These two option headers
are used to configure the various USB modes and speeds.
A MAX3353, configurable charge-pump applies the pull-up/pull-down resistor configuration un-
der program control. This charge pump also provides the OTG VBUS current when in HOST
mode. Pull-up and pull-down configuration may also be applied to the USB data lines inde-
pendently of the charge-pump. Refer to the USB2.0 specification for further details.
The OTG_EN option header connects the MAX3353 to the target MCU for programmatic con-
trol of USB lines for OTG applications. This header also allows signals to the MAX3353 to be
disconnected if not used. This prevents signal loading when the USB functionality is not re-
quired.

An ADM869L, hi-side switch, provides programmatic switching of output voltage for Host mode
USB applications. The part is configured for high current output to support a wide-range of
applications. The HOST_EN option jumper allows the target MCU to enable or disable USB
voltage output under program control. The hi-side switch also provides an active-low FAULT*
output to indicate failure.
