Internally not connected. 3 GND - N/A Ground All the GND pins are intended to be connected to ground 4 V_INT - O Generic Digital Interfaces supply output V_INT = 1.8 V (typical) generated by the module when it is switched-on, outside low power deep sleep mode. See section 4.2.3 for detailed electrical specs. Provide test point for diagnostic purposes. 5 GND - N/A Ground All the GND pins are intended to be connected to ground 6 DSR GDI O / I UART data set ready / AUX UART request to send Circuit 107 in ITU-T V.24 (DSR output, push-pull, idle high, active low), alternatively configurable as second auxiliary UART RTS (HW flow control input, idle high, active low, with internal active pull-up enabled). See section 4.2.14 for detailed electrical specs. 7 RI GDI O / O UART ring indicator / AUX UART clear to send Circuit 125 in ITU-T V.24 (RI output, push-pull, idle high, active low), alternatively configurable as second auxiliary UART CTS (HW flow control output, push-pull, idle high, active low). See section 4.2.14 for detailed electrical specs. 8 DCD GDI O / O UART data carrier detect / AUX UART data output Circuit 109 in ITU-T V.24 (DCD output, push-pull, idle high, active low), alternatively settable as Second Auxiliary UART RXD (data output, push-pull, idle high, active low). See section 4.2.14 for detailed electrical specs. 9 DTR GDI I / I UART data terminal ready / AUX UART data input Circuit 108/2 in ITU-T V. 24 (DTR input, idle high, active low, with internal active pull-up enabled), alternatively settable as Second Auxiliary UART TXD (data input, idle high, active low, with internal active pull-up enabled). See section 4.2.14 for detailed electrical specs. 10 RTS GDI I UART ready to send Circuit 105 in ITU-T V.24 (RTS flow control input, idle high, active low, with internal active pull-up enabled). See section 4.2.14 for detailed electrical specs. |
