GPIO Interface

ELS81-US offers a GPIO interface with 22 GPIO lines. The GPIO lines are shared with other
interfaces or functions: Fast shutdown (see 

Section 2.1.13.4

), status LED (see 

Section

2.1.13.1

), the PWM functionality (see 

Section 2.1.11

), an pulse counter (see 

Section 2.1.12

),

ASC0 (see 

Section 2.1.4

), ASC1 (see 

Section 2.1.5

), an SPI interface (see 

Section 2.1.10

). 

The following table shows the configuration variants for the GPIO pads. All variants are mutu-
ally exclusive, i.e. a pad configured for instance as Status LED is locked for alternative usage.

After startup, the above mentioned alternative GPIO line assignments can be configured using
AT commands (see 

[1]

). The configuration is non-volatile and available after module restart.
