For baseband operation, the X-GOLDTM102 supports:
• High Speed Circuit Switched Data (HSCSD) class 4
• Packet-oriented data (GPRS) class 4 with a coding scheme from 1 to 4. It provides fixed, dynamic,
and extended dynamic modes.
If the X-GOLDTM102 is only used as a modem, then it supports:
• High Speed Circuit Switched Data (HSCSD) class 10
• Packet-oriented data (GPRS) class 10 with coding schemes from 1 to 4. It provides fixed,
dynamic, and extended dynamic modes.
The X-GOLDTM102 can support Class B operation. The mobile phone can be attached to both
GPRS and GSM services (one service at a time). During a GPRS connection Class B enables
either:
• Making or receiving a voice call
• Sending or receiving an SMS.
During voice calls or SMS, GPRS services are suspended and then resumed automatically after
the call or SMS session has ended.
3.1.5 Bus Concept
The X-GOLDTM102 has two cores (a microcontroller and a DSP), each with its own bus.
There is an Shared memory interconnection between the TEAKlite bus and the C166S-V2 X-Bus.
C166S-V2 Buses
The C166S-V2 is connected to four buses:
1. IMB (Internal Program) bus
2. DPMI (Data-Program) Bus
3. X-Bus
4. PD-Bus.
TEAKLite Bus
The TEAKlite is connected to the TEAKlite bus.
Bus Interconnections
The interconnection between the X-Bus and the TEAKlite Bus uses:
• Multicore Synchronization
• Shared Memory.
3.1.6 Clock Concept
The X-GOLDTM102 has a flexible clock control.
3.1.7 Interrupt Concept
The C166 MCU carries out the X-GOLDTM102 interrupt system.
3.1.8 Debug Concept
The X-GOLDTM102 includes a multi-core debug. The C166 and TEAKlite cores can be debugged
in parallel with:
• A single JTAG port (that is, on a single host)
• Mutual breakpoint control.
