9 I/O Parallel Ports
Six lines of programmable bidirectional input/outputs (I/O) are provided. All the PIO lines are power from VDD.
PIO lines can be configured through software to have either weak or strong pull-ups or pull-downs. All PIO
lines are configured as inputs with weak pull-downs at reset. Any of the PIO lines can be configured as
interrupt request lines or as wake-up lines from sleep modes.
WT11i has a general purpose analogue interface pin AIO[1]. This is used to access internal circuitry and
control signals. It may be configured to provide additional functionality.
Auxiliary functions available via AIO[1] include an 8-bit ADC and an 8-bit DAC. Typically the ADC is used for
battery voltage measurement. Signals selectable at this pin include the band gap reference voltage and a
variety of clock signals: 48, 24, 16, 8MHz and the XTAL clock frequency. When used with analogue signals,
the voltage range is constrained by the analogue supply voltage internally to the module (1.8V). When
configured to drive out digital level signals (e.g., clocks), the output voltage level is determined by VDD.
9.1 PIO Defaults
Bluegiga cannot guarantee that these terminal functions remain the same. Refer to the software release note
for the implementation of these PIO lines, as they are firmware build-specific.
