Legend for Table 2-17:
With the GPIO_CFG0 signal on the rear I/O module an active COM2 or GPIO interface can be
selected.
Warning!
The RIO_XXX signals are power supply
OUTPUTS
to supply the rear I/O mod-
ule with power. These pins
MUST NOT
be connected to any other power
source, either within the backplane itself or within a rear I/O module.
Failure to comply with the above will result in damage to your board.
Note ...
The signal on the GPIO configuration pin D4 tolerates only 3.3 V signalling and
has an internal pull-up resistor to 3.3V.
The pins for the interfaces COM1 and GPIO/COM2 (pins A18, A17, A16, B18,
B17, B16, B10, B7, C18, C14, C13, C11, D18, D10, E18, and E16) tolerate
only 3.3 V signaling and their inputs have internal pull-up resistors.

DESCRIPTION
GPIO_CFG0
0 = GPIO
1 = COM2
Note ...
The default value is 1 if the pin is not connected (pull-up resistor on CP308). If
the pin is connected, the default value depends on the rear I/O module.
