User Guide

The radio has an automatic band search function, which can search for a strong write/read signal from a certain

frequency. When this is found, data is transmitted to the radio. When the signal strength is low, the TikuEDGE

can read data, which is available until the signal is strong again.

Camera

This device is equipped with a SVGA resolution camera. It is able to transfer up to 30 frames per second in

viewfinder mode and 15 frames per second in full resolution mode (SVGA).

The camera is connected to the Tiku via a hardware accelerator and a differential camera bus called CCP. The

control of the camera is routed through normal type general I/O ports. The camera uses both analoguee and

digital supply.

Tiku and UEMEK.

The interface in the UEMEK contains power up/down, port gating, card detect, data receiving, ATR-counter,

registers and level shifting buffers logic.

The data communication between the SIM card and the phone is asynchronous half duplex.
