    10. TERMINAL FUNCTION 1. SCL SCL terminal is a serial lock input terminal and used for TX/RX control between master and slave. 2. SDA SDA terminal is an input/output terminal and transfers the address sent from the master device to slave and mutual data. SDA output circuit employs the open drain, therefore the pull-up resistor is requ Terminal ired.

    When the bell signal is input between T/R, the signal is outputted at the speaker via the following path: Tel line R1/C1 Pin 1 of IC2/Pin 8 of IC2 Pin 5 of IC2 Ringer 11.2. Line Interface In talk mode, SW101 becomes ON and Q104 base becomes High, causing Q104 and Q102 to turn on and line loop is established.
  • Page 19 11.4. Initializing Circuit 11.4.1. Function: This circuit is used to initialize the CPU when the batteries are installed. 11.4.2. Circuit operation: When the batteries are inserted into the unit, the voltage is regulated by IC302 and power is supplied to the CPU. The unit starts operating soon after the voltage goes beyond the point A in the voltage diagram.

    SCK terminal is input terminal of Serial Clock to control transmit and receipt between Master and Slave. 2. SDA SDA terminal is input terminal, to forward the address and the mutual data between Master Device and Slave Device the mutual. This terminal needs the pull-up resistance external because output circuit of SDA uses Open Drain.
