5.3 ULP-COM sA3874i I/O
The ULP-COM sA3874i module provides multiple I/O lines for various functions. 12 I/Os lines are used as
interrupt capable GPIOs, which follow ULP-COM hardware specification. GPIO5 PWM output and GPIO6 Tachometer
input support is also provided as per the ULP-COM hardware specification.
Caution! These details are provided for reference. Generally, access to the I/O is abstracted in the Kontron BSP
packages.
GPIO functionality and I/O mapping to the ULP-COM sA3874i connector are shown in the following table:
