CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (LCD Driver)
4.7.4 Segment option
(1) Segment allocation
Up to 128 bits of the display memory can be selected from the data memory addresses F000H to
F01FH.
The LCD driver has a segment decoder built-in, and the data bit (D0–D3) of the optional address in
the display memory area (F000H–F01FH) can be allocated to the optional segment. This makes design
easy by increasing the degree of freedom with which the liquid crystal panel can be designed.
The allocated segment displays when the bit for the display memory is set to "1", and goes out when
bit is set to "0".
Figure 4.7.4.1 shows an example of the relationship between the LCD segments (on the panel) and the
display memory for the case of 1/3 duty.

Fig. 4.7.4.1 Segment allocation
At initial reset, the contents of the display memory are undefined, therefore it is necessary to initialize
by software. Since the display memory permits reading and writing, the addresses/bits that are not
used on the LCD display can be used as general-purpose registers.
(2) Output specification
The segment terminals (SEG0–SEG31) can be selected in pairs
for either segment signal output or
DC output (VDD and VSS binary output).
When DC output is selected, the data corresponding to COM0 of each segment terminal is output.
When DC output is selected, either complementary output or N-channel open drain output can be
selected for each terminal.
The terminal pairs are combination of SEG2 × n and SEG2 × n + 1 (where n is an integer from 0 to 15).
