Version: 1.2
6.1. Oscillator
SPLC780D oscillator supports not only the internal oscillator
operation, but also the external clock operation.
6.2. Control and Display Instructions
Control and display instructions are described in details as follows:
6.2.1. Clear display
It clears the entire display and sets Display Data RAM Address 0
in Address Counter.
6.2.2. Return home
X: Do not care (0 or 1)
It sets Display Data RAM Address 0 in Address Counter and the
display returns to its original position. The cursor or blink goes to
the most-left side of the display (to the 1st line if 2 lines are
displayed). The contents of the Display Data RAM do not
change.
6.2.3. Entry mode set
During writing and reading data, it defines cursor moving direction
and shifts the display.
I / D = 1: Increment, I / D = 0: Decrement.
S = 1: The display shift, S = 0: The display does not shift.
S = 1
I / D = 1
It shifts the display to the left
S = 1
I / D = 0
It shifts the display to the right
6.2.4. Display ON/OFF control
D = 1: Display on, D = 0: Display off
C = 1: Cursor on, C = 0: Cursor off
B = 1: Blinks on, B= 0: Blinks off
6.2.5. Cursor or display shift
Without changing DD RAM data, it moves cursor and shifts
display.
