Suitable for the dot matrix type LCD panel whose common/segment array is approximated to the bit array of the
display register. One of three types for the display register segment mapping can be selected, the numbe of used COM
pins determines the recommended type. See section 24.2.5, 24.2.9, and 24.3.2 for more detail.
When the programmable display function is not used, display allocation register A and display allocation register B
(See section 24.2.7 and 24.2.8) can be used as 1K-byte data memory.
DSPRFE
DSPRFD
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. Segment mapping of the display register can be assigned
in bit units by programming according to the contents of display allocation registers A and B. Therefore, the display
register array can be changed in flexible and simplify the software process for display. Contents of the registers
A(DSmCnA) specify addresses of the display registers (DSPR00 to FE) and contents of the registers B(DSmCnB)
specify bits of the display registers, that are output to common “n” of segment “m”.
