*GPIO line configured as input (default state)
Do not forget to configure the TX, MODE, and DIR lines as outputs. A pull-down
resistor on the MODE line ensures that the system boots up with the RS232 port
selected.
LED Control
The IB1004 works with a standard LB1001 board and controls the LEDs through 8
general-purpose I/O (GPIO) lines of the EM1000 module (installed on the NB10x0
network board). To turn the LED on, set the corresponding line LOW. Remember to
configure all LED control lines as outputs.
For all LED control lines:
HIGH (or input*) - LED off
LOW - LED on
