FUNCTIONAL DESCRIPTION
Power-On-Reset
The status of the internal circuit after power-on reset is as follows;
1) Shift registers and latches are reset.
2) PWM conversion mode is selected.
DATA Input
Data input is available only when the high level is applied to the "CS" pin. Input data is shifted
into shift registers through "Data" pin at the rising edge of the shift clock. The data is
automatically loaded to latches at the falling edge of "CS" signal. When M0 = "0", input data
should include display data (total of 64 bits data should be input.) and when M0 = "1", input data
should exclude display data (Total of 16-bit data shoul
[Data Format]
1) Display Data Input Mode
2) Segment outputs/Shift Registers Bit Correspondence Table
The content of the table depends on a PLA code.
This table is modeled on the general purpose code of -01.
Segment output positions can be changed dependent on the PLA code, but the segment-bit
correspondence cannot be changed.
