DSP CONTROLLER (IC5208 12pin, 22pin) sends reset signals to
DSP1 (IC5002 B10pin) and DSP2 (IC5202 B10pin).
DSP1 (IC5002) starts to read the operation firmware from FLASH
MEMORY (IC5006). This FLASH MEMORY is called “DSP Parallel

(IC105) starts to read the operation firmware which is stored in itself.
UPDATE SIGNAL PROCESSOR (IC105) analyzes input remote
commander signals and stored the result in itself. Therefore, the stored
data is also read when UPDATE SIGNAL PROCESSOR boots up.
