SPLC782A

5. FUNCTIONAL DESCRIPTIONS

5.1. Oscillator

The built-in RC oscillator generates suitable clock for SPLC782A

operation.

5.2. Control and Display Instructions

Control and display instructions is shown as follows:

S=1

I/D=1

It shifts the display to the left

S=1

I/D=0

It shifts the display to the right

s E X: Do not care (0 or 1)

lu IN It sets display data RAMs address 0 in address counter and

p display returns to its original position. The cursor or blink goes to

n M the left edge of the display (to the 1st line if 2 lines are displayed).

u T The content of the Display Data RAM does not change.

S R 5.2.3. Entry mode set

A During writing and reading data, it sets cursor move direction and

P shifts the display.
