● Counter select resister
The 1 bit data stored in this register selects X−address counter or Y (Page) −address counter.
● Display ON / OFF register
This 1 bit register holds the display ON or OFF state. In the OFF state, the output data turn to V
In the On state, the display data appears according to the display RAM data. The display ON or OFF state
does not affect the data of display RAM.
● Z−address register
This 6 bit register holds the data that indicates the display start line.
● Word length register
The 1 bit data stored in this register selects the word length, 8 bits per word or 6 bits per word.
● Word length change circuit
This circuit is controlled by the word length register. In case of 8 bits per word, data is transferred by 8 bits.
In case of 6 bits per word, the way of data transfer is show in Fig. 2 as follows.
● Oscillator
The T6K04 has an on−chip oscillator. When using this oscillator, connect an external resistor between OSC1
and OSC2, when using external clock, input the clock to OSC1 and open OSC2, as shown in Fig. 3.
● Timing generation circuit
The circuit divides the signals from the oscillator and generates display timing signals and operating clock.
● Shift−register
The T6K04 has two 32 bit shift−register. These shift−register construct 64 bits shift−register.
● Latch circuit
This latch circuit latches the data from the display RAM.
