Built-in Reset Circuit
The ML9044 is automatically initialized when the power is turned on.
During initialization, the Busy Flag (BF) is “1” and the ML9044 does not accept any instruction from the CPU
(other than the Read BF instruction).
The Busy Flag is “1” for about 15 ms after the V
DD becomes 2.5 V or higher.
During this initialization, the ML9044 performs the following instructions:
1)
Display clearing
2)
CPU interface data length = 8 bits
(DL = “1”)
3)
1-line LCD display
(N = “0”)
4)
Font size = 5
× 7 dots
(F = “0”)
5)
ADC counting = Increment
(I/D = “1”)
6)
Display shifting = None
(S = “0”)
7)
Display = Off
(D = “0”)
8)
Cursor = Off
(C = “0”)
9)
Blinking = Off
(B = “0”)
10) Arbitrator = Displayed in the lower line
(AS = “0”)
11) Setting 1FH (hexadecimal) to the Contrast Data
To use the built-in reset circuit, the power supply conditions shown below should be satisfied. Otherwise, the
built-in reset circuit may not work properly. In such a case, initialize the ML9044 with the instructions from the
CPU. The use of a battery always requires such initialization from the CPU. (See “Initial Setting of Instructions”)
