Row/Column Output Switchover:
LCD column drivers use V
CC
, V2, V3, and V5, while row drivers use
V
CC
, V1, V4, and V5. These voltage levels are switched to AC and are output to an LCD panel. Since the
HD66410 can assign X1 to X16 and X129 to X144 to either row or column output, the power supply
connection must be externally changed according to the assignment, which is determined by the CNF bit
value in control register 1. The select and deselect levels for row output are temporarily output from the
VCHO and VCLO pins, and the two levels for column output are output from the VSHO and VSLO pins;
these outputs must be connected according to row and column output assignment as shown in Figure 25.
