Block Functions

Oscillator

The CR oscillator generates display timing signals and operating clocks for the HD61202U. It is required

when the HD61203U is used with the HD61202U. An oscillation resister Rf and an oscillation capacitor

Cf are attached as shown in Figure 1. When using an external clock, input the clock into terminal CR and

don’t connect any lines to terminals R and C.

The oscillator is not required when the HD61203U is used with the HD61830. Then, connect terminal CR

to the high level and don’t connect any lines to terminals R and C (Figure 2).
