2.1.5 GPIO Interface
PLS62-W offers a GPIO interface with 24 GPIO lines. The GPIO lines are shared with other
interfaces or functions: Fast shutdown (see Section 2.1.11), status LED (see Section 2.1.10),
the PWM functionality (see Section 2.1.8), an pulse counter (see Section 2.1.9), ASC0 (see
Section 2.1.2), ASC1 (see Section 2.1.3), an SPI interface (see Section 2.1.7).
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.
