HD61602/HD61603
Operating Modes
HD61602 Operating Modes
The HD61602 has the following operating modes:
1. LCD drive mode
2. Data display mode
3. READY output mode
4. LCD OFF mode
5. External driving voltage mode
The above 5 modes are specified by mode setting data. The modes are independent of each other and can
be used in any combination. Bit manipulation is independent of data display mode and can be used
regardless of it.

Determines the LCD driving method.
a. Static drive mode
b. 1/2 duty cycle drive mode
c. 1/3 duty cycle drive mode
d. 1/4 duty cycle drive mode
Determines how to write display data into the data RAM.
a. Static display mode
b. 1/2 duty cycle display mode
c. 1/3 duty cycle display mode
d. 1/4 duty cycle display mode
Determines the READY output timing.
After a data set is transferred, the data is processed internally. The next data cannot be acknowledged
during the processing period. The READY output reports the period to the MPU. The timing when the
READY is output can be selected from the following two modes:
a. READY is mode always available (Figure 12).
b. READY is mode available by
In this mode, the HD61602 stops driving LCD and turns it off.
A mode for using external driving voltage (V1, V2, and V3).
LCD is driven statically.
LCD is driven at 1/2 duty cycle and 1/2 bias.
LCD is driven at 1/3 duty cycle and 1/3 bias.
LCD is driven at 1/4 duty cycle and 1/3 bias.
8-bit data is written into the display RAM according to the digit in static drive.
8-bit data is written into the display RAM according to the digit in 1/2 duty cycle drive.
8-bit data is written into the display RAM according to the digit in 1/3 duty cycle drive.
8-bit data is written into the display RAM according to the digit in 1/4 duty cycle drive.
