MCIDAT1

Connects to MCIDAT1 on SD/MMC connector

MCIDAT2

Connects to MCIDAT2 on SD/MMC connector

MCIDAT3

Connects to MCIDAT3 on SD/MMC connector

GPIO41

GPIO_05

No special usage on OEM Base Board, but is used for

SPI_SSEL on the boot serial flash on the LPC3250 OEM

board

GPIO42

GPO_14

Connects to LCD expansion connector (backlight control).

Connects to USB1-up LED (active low).

Connects to serial expansion connector.

GPIO43

GPI_03

Connects to RS422/485 transmit/receive control.

Can optionally be connected to USB1 VBUS power enable.

Note that the LPC3250 cannot control these functionalities

on the OEM base board since GPIO43 is connected to an

input (GPI_03) on the LPC3250.
