1. CPU INTERFACE 
1-1. Serial Interfaces 
Fig.1-1 shows the serial interfaces of the model. 
 
1. Communication between System Controller IC101 and Real Time Clock, X801 
System Controller IC101 obtains the clock data via the serial communication.   
 
One Point: 
            Real Time Clock, X801 keeps oscillating even if the unit is in the sleep mode. 
 
2. Communication between System Controller IC101 and Tuner IC2702 
System  Controller  IC101  controls  the  Tuner  IC2702  by  outputting  the  various  serial  commands.  These  serial  commands  are  output  from  pin-133  [TU_DA]  in 
synchronization with the clock of pin-134 [TU_SCK] and the latch signal of pin-135 [TU_LA]. IC2702 starts the corresponding operation to the command input when the 
latch signal is “L”. Also Tuner IC2702 outputs the status signal from pin-13 [STO] to System Controller IC101. 
 
The main interfaces are described below. 
[IC101 -> IC2702] 
 Internal Reset 
 Mute Control 
 Band Preset 
 
The main status signal contents are described below. 
[IC2702 -> IC101] 
 Stereo / Mono 
 Electric field strength of the received signal 
 
3. Communication between System Controller IC101 and PC 
The unit has the USB terminal to perform the data communication with PC. System Controller IC101 operates the serial communication with PC through the following 
input / output terminals.   
 
 System Controller IC101 pin-126 [DM] (D-) 
 System Controller IC101 pin-125 [DP] (D+) 
 
            One Point: 
            The unit supports to USB2.0 (High Speed).
