• Manufacturer Part Number: S1D1
• Description: LCD Controller-driver With Built-in Character ROM
• Manufacturer: Epson Electronics America, Inc.

When the DUTY + 1 command is executed, pin COM1
becomes as shown in Figure 4 irrelevant to output selec-
tion:
Since master/slave operation and the output selection
circuit are completely independent in the S1D15600/
601/602 series, a chip either on the master or slave side
When COM outputs are assigned to the output drivers,
the unused RAM area is not available. However, all
RAM column addresses can still be accessed by the
microprocessor.
Since duty setting and output selection are independent,

the appropriate duty must be selected for each case.
Cases 1 to 6 are determined according to the three lowest
bits in the output status register in the output selection
circuit. The COM output scanning direction can be
selected by setting bit D3 in the output status register to
HIGH or LOW.
can be allocated to the COM output function in multi-
chip configuration.
The LCD driver outputs shown in Table 5 become
ineffective when the S1D15600 or S1D15601 is used
with 1/48 or 1/24 duty, respectively. In this case,
ineffective outputs are used in the open state.
