As same as write mode , user has to sent address three times. And read data from RAM one by one which
address can be increased by internal counter. NOTE!! Be sure to make RAMR low pulse 2

width and 2

S (Tdd) high width at least.
(5) RAM mapping
RAM address is from 0 to address 2559
User fill “1” to LCD RAM , LCD driver will generate “l(fā)ight” waveform. Otherwise , it will generate a
“dark” waveform. The LCD RAM area is mapped to segment 1 to segment 80 from address 0 to address
19. And user can refer to fig.5 to get the idea of LCD ram mapping. The other RAM can use as general
RAM for data storage. And the RAM of address 2560 is a control register.
