Reset Function
Initializing by Internal Reset Circuit
The
HD66705U
is internally initialized by RESET input. During reset, the system executes the instructions as
described below. Here, the busy flag (BF) therefore indicates a busy state (BF = 1), accepting no instruction
or RAM data access from the MPU. Here, reset input must be held at least 10 ms.
After releasing power-on reset, clear display instruction is operated, so wait for 1,000 clock-cycles or more.
Make sure to reset the
HD66705U
immediately after power-on rese.
1. Instruction set initialization
a. Clear display:
Writes 20H to DDRAM and wait for 1,000 clock-cycles or more after releasing reset
b. Return home
Sets the address counter (AC) to 00H to select the DDRAM
c. Start oscillator
d. Entry mode
I/D = 1: Increment by 1
OSC = 0: Clock frequency not divided
e. Cursor control
B/W = 0: White-black inverting cursor off
C = 0: 8th raster-row cursor off
B = 0: Blink cursor off
f.
Display on/off control
DC = 0: Character display off
DS = 0: Segment display off
LC = 0: Line-cursor off
g. Power control
AMP = 0: LCD power supply off
SLP = 0: Sleep mode off
STB = 0: Standby mode off
h. Display control
DL = 0: Double-height display off
i.
Contrast adjust
CT = 0000: Weak contrast
j.
Scroll control
SN2–SN0 = 000: First line displayed at the top
SL2–SL0 = 000: First raster-row displayed at the top of the first line
