2.1.8 Analog-to-Digital Converter (ADC)
ADC1_IN is used for general purpose voltage measurements. ADC1_IN can be configured and
read by AT command - see [1].
2.1.9 PWM Interfaces
The GPIO6 and GPIO7 interface lines can be configured as Pulse Width Modulation (PWM)
interface lines PWM1 and PWM2. The PWM interface lines can be used, for example, to con-
nect buzzers. The PWM1 line is shared with GPIO7 and the PWM2 line is shared with GPIO6
(for GPIOs see Section 2.1.5). GPIO and PWM functionality are mutually exclusive.
2.1.10 Pulse Counter
The GPIO8 line can be configured as pulse counter line COUNTER. The pulse counter inter-
face can be used, for example, as a clock (for GPIOs see Section 2.1.5).
2.1.11 Control Signals
2.1.11.1 Network Connectivity
The STATUS line serves to indicate the module’s network connectivity state and can be used
to control an externally connected LED.
2.1.11.2 Power Indication Signal
The power indication signal PWR_IND notifies the on/off state of the module. High state of
PWR_IND indicates that the module is switched off.
2.1.11.3 Host Wakeup
If no call, data or message transfer is in progress, the host may shut down its own USB inter-
face to save power. If a call or other request (URC’s, messages) arrives, the host can be noti-
fied of these events and be woken up again by a state transition of either the RING0 or the
GPIO4 line configured as H_WAKEUP line.
2.1.11.4 Fast Shutdown
The GPIO4 interface line can be configured as fast shutdown signal line FST_SHDN. The con-
figured FST_SHDN line is an active low control signal and must be applied for at least 45 mil-
liseconds. If unused this line can be left open because of a configured internal pull-up resistor.
