Gpio Signal Description - Kontron CP3002 User Manual

Functional Description
General Purpose Inputs/Outputs
Alternatively, the following GPIO signals are available instead of the COMB signals if pin D4 on
the rear I/O connector J2 (GPIO_CFG0) is set to 0.
Table 2-19: GPIO Signal Description
PIN on J2 SIGNAL
B10 GPO0
B17 GPI0
D18 GPI1
C14 GPO1
B7 GPI2
C11 GPI3
D10 GPO2
C13 GPI4
Note ...
The pins for the GPIO interface (pins B17, B10, B7, C14, C13, C11, D18, and
D10) tolerate only 3.3 V signaling and their inputs (driven by the rear I/O mod-
ule) have internal pull-up resistors.
VGA Interface
VGA signals are available either on the front VGA connector, J6, or on the rear I/O interface
due to the implemented switch on the CP3002. Switching over from front to rear I/O or vice
versa is effected using the uEFI BIOS or the board-specific Control Register 0 (0x282), bit 7-6
(default: front I/O).

PIN on J2 SIGNAL
C10 VGA_RED
C6 VGA_GREEN
C8 VGA_BLUE
C9 VGA_HSYNC
C5 VGA_VSYNC
C4 VGA_DDC_CLK Monitor control clock signal
C7 VGA_DDC_DATA Monitor control data signal
Note ...
On the rear I/O, the CP3002 provides 150  termination resistors for the red,
green and blue VGA signals. Thus, further 150  termination resistors are
necessary on the rear I/O module to reach the required 75  termination for
the VGA connection.
