How to Use the SHL Pin
It is possible to invert the relationship between the addresses and output pins Y1 to Y160 by setting the
SHL pin (Figure 8). The upper left section on the screen can be assigned to address H'00000 regardless of
which side of the LCD panel the HD66522 is connected to.
The Relationship between the Data Bus and Output Pins
The 8-bit data on the data bus has a 2-bit/pixel configuration for a 4-level grayscale display. In addition, the
8-bit data on the data bus has a relationship as shown in table regardless of the relationship between pins
LS0, LS1, LS2 and SHL. Since the relationship between data bus pins DB0 to DB7 and the output location
are fixed, connect the data from the CPU directly to data bus pins DB0 to DB7.
