MAS_SLV FP_PP Mode HL PA receiver H H PA transmitter L L TG transmitter LH TG receiver 34 FP_PP I - I-PD 35 VOL_DN I - I-PD PP: Volume Down input. Connect to Volume Down pushbutton. FP: Must be unconnected. 36 VOL_UP/ MUTE I - I-PU PP: Volume Up input. Connect to Volume Up pushbutton. FP: Mute input. When this pin is pulled LOW the FP will mute all audio to/from the PP. 37 NC - - - Must be unconnected. 38 GND - - - Ground 39 NC - - - Must be unconnected. 40 REGION1 - - I-PU Selection of DECT RF frequency (FP and PP). REGION1 REGION2 RF BAND L L DECT 6.0 (USA) LH Reserved H L Japan DECT H H European DECT 41 REGION2 - - I-PD 42 LED_RED2 O 8 I PA FP: Red LED 2 output (see section 5.0). Connect to VDDOUT via a series resistor (typ. 39 . Other modes: Must be unconnected. 43 RF_POWER I - I-PU RF Power mode selection input. High Power Mode (HPM): leave unconnected. Low Power Mode (LPM): connect to GND. 44 NC - - - Must be unconnected. 45 GND - - - Ground 46 NC - - - Must be unconnected. 47 UART_RX I - I-PD (10k) UART RX input, debug purposes. 48 UART_TX O 8 - UART TX output, debug purposes. 49 GND - - - Ground 50 GND - - - Ground 51 GND - - - Ground 52 RSTn I 1 I-PU (200k pull-up) Active low Reset input with Schmitt-trigger input, open-drain output and pull-up resistor to internal VDD. Input may not exceed 2.0 V. An internal capacitor of 47 nF is mounted on this pin. 53 JTAG - - - Debug purposes. Internally connected to VDDOUT (pin 61) via a 1k resistor 54 NC - - - Must be unconnected. 55 NC - - - Must be unconnected. 56 NC - - - Must be unconnected. 57 NC - - - Must be unconnected. 58 LED_RED1 O 8 I Red LED output 1.
