Clock signal to transfer the line data to an LCD
display driver block.
Scan function data to select LCD driver output
level
Control signal to fix LCD driver outputs to LCD
deselect mid level. When low, LCD drive outputs
Y1 to Y160 are set to VM. Display can be turned
off by setting a common driver to VM.
Setting this pin low initializes the HD66522
Upper 9 bits (A16–A8) are used for the duty-
directional addresses, and lower 8 bits (A7–A0)
for the output-pin directional addresses (refer to
Pin Functions
for details).

Status output signal
Each Y outputs one of the three voltage levels
VCH, VM or VCL, depending on the combination
of the FX0 or FX1 signal and data levels.
