These bus lines are used for optical circuit control of
projection TV. EURO5 chassis has 3 bus line, EURO5-VP
chassis is operated by 4 bus line.
Pin No. 76
During the digital convergence mode, digital convergence
circuit is operated by SUB MPU(IC7106).
During that time, Main MPU(IC1101) is stopped by Hi
