20. General Purpose I/O (GPIO) Pin related Commands
This chapter describes the AT commands used to access and configure the GPIO pins of EHS6.
Please also refer to [2] for electrical specifications of the GPIO pins.
20.1 AT^SCPIN Pin Configuration
The AT^SCPIN write command serves to add (or remove) and configure GPIO lines. Keep in mind that some
GPIO lines share functions with other interfaces. For details see AT^SCFG "GPIO/mode/xxx" settings, Section
20.1.1, GPIO Configuration Table and following AT commands: AT^SLED, AT^SCCNT, AT^SWDAC, AT^SSPI,
AT^SCFG "MEShutdown/Fso".
