Each of the examples in the BSP includes source files that program the soft
switches, even if the default settings are being used. The README for each
example identifies only the signals that are being changed from their
default values. The code that programs the soft switches is located in the
SoftConfig_LCD.c file in each example.

shows how the GPIO expander is connected to the board’s ICs.
U14–16
are 24-bit bus switches. The switches select how the LCD module
is connected to the processor. You can select a 16-, 18-, or 24-bit
interface.
U31–41
are 2-port bus switches. The switches select the GPIO signals to be
used as interrupts and SPICS signals to connect to various IC on the
extender.
The U44–45 switches select the interface to communicate with the acceler-
ometer: SPI or TWI.
Table 2-1 through Table 2-6 show the output signals of the GPIO
expander ( U10 ) with a TWI address of 0100 111 X , where X represents the
read or write bit. The signals that control an individual FET have an entry
