EM65565A
When plural EM65565A chip are used. The slave chips must be supplied the display
timing signals (FR, DCLK, /BCT) from the master chip(s). Explain as following Table 5.

Note: When the EM65565A is used for the master/slave configuration, each of the DCLKS pins is set to
the same level together.
The Common Output Status Select Circuit
In the EM65565A chip, the COM output scan direction can be selected by the common
output status select command. (See Table 6.) Consequently, the constrains in IC layout at the
time of LCD module assembly can be minimized.

The LCD Driver Circuits
These are a 197-channel that generates four voltage levels for driving the liquid crystal.
The combination of the display data, the COM scan signal, and the FR signal produces the
liquid crystal drive voltage output. Figure 7 shows examples of the SEG and COM output
waveform.
