Chapter 22 LCD Drivers
A) When not using Programmable display allocation function (DASN bit of DSPMOD1 register is “0”)
B) When using Programmable display allocation function (DASN bit of DSPMOD1 register is “1”)
Suitable for the dot matrix type LCD panel whose common/segment array is approximated to the bit array of the display
register.
Figure 22-2 shows an example of the correlation between the display registers and the dot matrix type LCD image.
The programmable display allocation function is suitable for the LCD panel of segment type or character type whose
common/segment array is restricted by the design or wiring. The display allocation registers A and B can be used to
programmatically specify the display register bit-by-bit. This allows the display registers to be arrayed flexibly and thus
makes the display processing in the software easier. The content of the display allocation register A (DSmCn) specifies
the addresses of the display registers (DSPR00 to 27) to be output to the common "n" of the segment "m." The content
of the display allocation register B (DSmCnB) specifies the bits of the display registers (DSPR00 to 27) to be output to
the common "n" of the segment "m."
Figure 22-3 shows an example of the correlation between the display registers and the dot matrix type LCD image when
the programmable display allocation is used.
