FUNCTIONAL DESCRIPTION
l
Power-on Reset
The built-in Power-on-Reset (POR) circuit initializes the internal circuits when power is applied.
The following condition is established after POR.
1) Contents of the shift register and latches are "0".
2) Duty cycle of digital dimming is set to "0".
3) All the outputs are OFF.
l
Function Mode
The function mode is selected according to the output of the last bit of the shift register.
The function modes are as follows.
M0 (Last bit)
0
1
Function
Digital dimming data input mode
Display data input mode
l
Digital Dimming Data Input
When M0="0", the digital dimming data input mode is selected and the input data length is 16
bits.
The digital dimming data input is valid only when the low level is applied to the
CS
pin.
The digital dimming data that was input to DATA-IN is input into the shift register at the rising
edge of the CLOCK.
Data is automatically loaded to the latches from the shift register at the rising edge of
CS
.
The digital dimming data consists of 10 bits.
The output duty varies from 0/1024 (0%) to 1016/1624 (99%) for each grid.
The 10-bit digital dimming data should be input starting with the LSB.
