COMe-mSP1 / Features and Interfaces

4.9 GPIO - General Purpose Input and Output

The offers 4 General Purpose Input (GPI) pins and 4 General Purpose Output (GPO) pins. On a 3.3V level digital in- and

outputs are available.

Signal Pin Description

GPI0 A54 General Purpose Input 0

GPI1 A63 General Purpose Input 1

GPI2 A67 General Purpose Input 2

GPI3 A85 General Purpose Input 3

GPO0 A93 General Purpose Output 0

GPO1 B54 General Purpose Output 1

GPO2 B57 General Purpose Output 2

GPO3 B63 General Purpose Output 3

Configuration

The GPI and GPO pins can be configured via JIDA32/K-Station. Please refer to the JIDA32/K-Station manual in the driver

download packet on our customer section.

To enable GPIO functionality, modules with HW revision CE 1.x.x must be reworked. Contact

your local sales or support for further information. On modules with HW revision CE 4.x.x

and BIOS R115 or newer GPIO/SDIO can be switched via BIOS setup option

The General Purpose Inputs and Outputs are not applicable to drive applications faster than

2ms. It’s recommended to use data transfer rates only up to 1 kHz.

General Purpose Outputs are high impedance until first write access

There is one IO Port controlled via onboard CPLD (1 Byte, Port 0) available and the 4 Inputs and 4 Outputs are fixed in

direction. To access the GPIOs use the JIDA32 interface. You can write to a General Purpose Output with the upper half

byte. To read a General purpose Input use the lower half byte.
