Product specification

TDA3602

The timing diagram can only be understood after a

thorough investigation of the flow charts (see section Flow

chart semi on/off logic with security code). Furthermore

short and long RESET pulses can be seen (see Fig.12).

Flowchart semi on/off logic with security code

This section describes the software for controlling the

TDA3602 (semi on/off logic). A “o” in the flowchart flow

diagram Fig.13, indicates that the port mentioned is

switched as an output. A “1” indicates that the port

mentioned is switched as an input (temporarily).

The flowchart of figure 13 can be used for semi on/off logic.
