“2A”, and so on.
Controls whether the data of D30~D55 are inverted or not, same as REV1.
Clock input; latching data onto the line latches at the rising edge.

I/O
Start pulse signal input/output
When SHL is applied high (SHL="1"), a start high-pulse on DIO1 is latched at the rising edge of the
CLK. Then the data are latched serially onto internal latches at the rising edge of the CLK. After all
line latches are filled with data, 67 clocks, a pulse is shifted out through the DIO2 pin at the rising
edge of the CLK. This function can cascade two or more devices for dot-size expansion. In normal
applications, the DIO2 signal of the first device is connected to the DIO1 of the second stage, the
DIO2 of the second one is connected to the DIO1 of the third, and so on, like a daisy chain.
In contrast, when SHL is applied low, a start pulse inputs on DIO2, and a pulse outputs through
DIO1.
*Remark: The input pulse-width of DIO1/2 may exceed 1 clock-cycle.
I
Latches the polarity of outputs and switches the new data to outputs.
1. At the rising edge, latches the “POL” signal to control the polarity of the outputs.
2. The pin also controls the switch of the line registers that switches the new incoming data
to outputs.
*Remark: The LD may switch the new data to outputs at anytime even if the line data are not
completely full.
I
Polarity selector for the dot-inversion control. Available at the rising edge of LD
“POL” value is latched at the rising edge of “LD” to control the polarity of the even or odd outputs.
“POL=1” indicates that even outputs are of positive polarity with a voltage range from V1~V5, and
odd outputs are of negative polarity with a voltage range from V6 to V10. On the other hand, if LD
receives low level “POL”, even outputs are of negative polarity and odd outputs are of positive
polarity.
POL=1: Even outputs range from V1 ~ V5
Odd outputs range from V6 ~ V10
POL=0: Even outputs range from V6 ~ V10
Odd outputs range from V1 ~ V5
