The Gate Array IC(IC301) works only for writing the ASCII code from the data bus (D4~D7). V0 is supplied for the crystal drive.
R312, R313, R314 and R316 are density control resistors.
Consequently, in this unit, the timing (positive clock) is generated by the LCD interface circuitry in the gate array (IC301).
