As discussed in the previous section, GPIOs 3 through 8 are set by default for special functions such as modem controls. To use GPIOs 3 through 8 as normal GPIOs, you must place a jumper between JP7 and JP8 for the specific GPIO as described in the previous section. GPIO 2 can also have a special function if SPI mode is selected for the LCD display via header JP12 as described in the LCD Interface section later in this chapter.

GPIO_3	GPF 3	O	Special function TEMP_CS SPI temperature sensor enable
GPIO_4	GPF 4	O	Special function, nDTR0
GPIO_5	GPF 5	I	Special function, nDSR0
GPIO_6	GPF 6	I	Special function, nDCD0
GPIO_7	GPF 7	O	Special function, nLED_3; wired link
GPIO_8	GPG 5	O	Special function, nLED_2; wireless link
GPIO_9	GPG 6	O	nLED_1; power on/status*

GPIO_10	GPG 7	I	Switch Input; 1 = off, 0 = switch depressed*

*The functionality of GPIO_9 and GPIO_10 cannot be changed by the user.

LEDs and General Purpose I/O Signals

The LEDs are connected to the 10 GPIOs for easy viewing of signal activity. The first 7 GPIOs drive the first 7 LEDs, D1 to D7 (these LEDs indicate the status of the GPIOs). GPIOs 7 to 9 drive LEDs D8 to D10. Logic 0 and 0 volts on GPIO_x illuminates the LED.
