Figure 2 shows the possible design of a custom COF with wire on array (WOA) routing
(PCB-less). This example supports only 480 outputs.

Description
Clock input for the chip internal shift register. Data
is shifted at each rising edge of this clock.
This pin controls the output shifting direction.
These pins are used to control the channel start
pulse input or output pin. The function of these
two pins depends on the status of DIR pin (refer
to the Section 3: Truth tables)
This pin is used to control the channel output.
When BLANK is high, the shift register is
bypassed (overriden) and all driver outputs are
fixed to VN level instantly, (when POL= L).
It is assumed this signal affect few outputs
