3.6. Incoming Call Line Identification (CLI)
When a call is received the last six digits of the CLI information is matched with the phonebook. Therefore an incoming call could be matched to the wrong phonebook entry.
3.7. Hot Key Dial Source List
The source for Hot Key Dial Numbers is normally 'Phonebook' or 'Service Dial Numbers'. For some OEMs it may be a requirement to store these numbers in Flash-ROM. When the source is the Flash-ROM and the telephone software is updated, the source numbers may be lost. Also, if the user changes the source of the Hot Key Dial numbers, it will not be possible to redirect the source back to Flash-ROM. However, in the event that an OEM would like the Hot Key Dial source to be stored in the Flash-ROM, it is unlikely that the user will have the option to change the Hot Key Dial source.
3.8. Public Man Machine Interface (MMI)
3.8.1. General
It is possible to operate all GSM telephones in the same way using the Public MMI. The following operations will work with all GSM telephones. However, this information is restricted to those operations supported by the telephone.
The * and # in the following procedures should be replaced by and respectively. Also <SND> and <END>
should be replaced with and keys.

Figure 5.4. Baseband Block Diagram
The EB-X500 Baseband is built around a GSM chipset developed by Texas Instruments. One chip (Calypso_G2) carries out signal processing with DSP and CPU, and the other chip (IOTA) provides the analogue interface. The highly integrated nature of the chips means that each can contain a large number of functions.

5.3. Keypad
The Keypad has a 5 x 5 matrix, allowing 25 keys to be scanned. When a key is pressed, a keypad interrupt is generated. To find which key has been pressed, the software scans each column in turn and reads which row is active. Because of key bounce, the key press is confirmed twice at approximately 20 ms intervals.

Keyboard scanning is controlled by software. "Key pressed" is indicated by an interrupt, but "key released" is monitored bysoftware.
5.4. Subscriber Identity Module (SIM)
To allow the use of both 1.8 V and 3 V SIM types, a SIM level-shifter module in the TWL3014 device interfaces the SIM signals (DBBSRST, DBBSIO, and DBBSCK) at a constant VRIO level from the DBB device with the SIM card (SIMRST, SIMIO, and SIMCK) at a 1.8V or 3V level depending on SIM type.
5.5. TPU
The TPU is a real time sequencer dedicate to the monitoring of GSM baseband processing. Working from an event table referring to a GSM TDMA time base, the TPU activates takes to control DSP peripheral with respect of the time constraints related to the GSM sequencing. To store the real time microinstructions of the sequencer, the TPU includes one 2 ports RAM of 1024 words of 16 bits with a dual page addressing capability.

EB-X500 uses a 730 mAh Lithium-ion battery pack.
5.8. Battery Temperature (BATTEMP)
The battery packs used for EB-X500 contain a negative temperature coefficient thermistor. The basic parameters of the thermistor are 10 KΩ.
5.9. LCD
The LCD module consists of a LCD glass and driver chip connection to the Main PCB via a flexible PCB strip. A 128 x RGB x 128 pixels graphical display is used which can display up to 16 characters x 6 rows-plus two rows of icons. It can accommodate Chinese and large character sets. Features:
8 Color Amorphous Silicon TFT 1.6inch display module for mobile phones, or handy electrical equipments. 8 128 x 128 pixels up to 65K colors. 8 Transflective type 8 TN mode. 8 Line inversion mode 8 18bit CPU interface. 8 Constructions: 8 Display format: Color TFT transflective type 8 Display mode: Normally White 8 Display composition: 128 x RGB x 128 pixels 8 Drive system: a-Si TFT active matrix 8 Liquid Crystal: TN mode 8 Back light: LED x 2

The LCD driver is controlled by setting the command register through the G2 u-wire interface and an I/O line, which distinguishes between command or data. To send data or a command to the display driver, the nCS2 line is used for chip select. LCDA0 (I/0 3) is set high to send data and set low to send commands.
5.10. Real Time Clock (RTC)
Clock Functions are provided by the Real Time Clock is built into G2. The module is synchronised by a 32.768 kHz crystal and has a backup power source provided by a button battery. G2 has a clock auto compensation function to take into account any inaccuracies of the crystal. This is able to calibrate out crystal tolerance / drift by writing to the compensation registers. This calibration can provide adjustments ± 555.6ppm in 0.0085 ppm increments.
