FUNCTIONAL DESCRIPTION
Power-on Reset
When power is turned on, the IC is initialized by the internal power-on reset circuit. The status
of the internal circuit after initialization is as follows:
–
The contents of the shift registers and latches are set to "0".
–
The digital dimming duty cycle is set to "0".
Data Input
Data input to the DATA-IN pin is valid only when the
CS
pin is at a "L" level.
The input data to DATA-IN is shifted into the shift registers on the rising edge of the clock. The
data is automatically loaded to the latches on the rising edge of the
CS
pin.
When M0 = "1", the IC enters the display data input mode and a total of 112 bits of data are input.
When M0 = "0", the IC enters the digital dimming data input mode and a total of 16 bits of data
are input.
