19 CIRCUIT OPERATION (Handset)

19.1. Construction

The circuit mainly consists of DSP and RF unit as shown in the block diagram.

19.1.1. DSP:IC201

19.1.1.1. Function

Battery Low, Power down defect circuit

Ringer Generation

Interface circuit

RF unit, speaker, mic, LED, Key scan, LCD, Headset

19.1.1.2. The Meaning of the Motion of Pin 100

The period of Host Power Up (Hardware Initialization)

In this period, the host sets up some registers in order to wake up the system.

The period of Host Reset (Software Initialization)

In this period, the host reads the parameter from the memory and initializes module.

19.1.2. RF unit

Mainly voice signal is modulated to RF, or it goes the other way.

19.1.3. EEPROM: IC202

All setting data is stored.

ex: ID code, user setting (Flash Time, Tone/Pulse)
