13-4-3 SYSCON/SERVO Block H/W demand matter
At SYSTEM/SERVO BLOCK, it is TMP1962. It is each BLOCK at 32BIT 1MByte MICRO
PROCESSOR.CONTROL(ing) IC and a circuit, MAIN CLOCK uses 13.5Mhz(es).
RTC use of the exception way for SUB CLOCK LITHIUM BATTERY 3V BACK UP functional execution is
carried out. MICOM to PWM PULSE for MOTOR control and an ON/OFF CONTROL signal are
inputted, and the phase and speed of DRUM of DD-10 DECK and CAPSTAN MOTOR are controlled by
SERVO Block.
Moreover, input of the various kinds SENSOR of DECK (TOP/END, T/S REEL, Media Interface
Connector SW, RECPROOF, CC LOCK Etc) is carried out, and micom is made to print out.
Made to REGULATION LOADING MOTOR 4.7V VS.
