This area is lo- cated from 40H to 60H of the RAM at Bank 1. Bank pointer (BP; located at 04H of the RAM) is the switch between the RAM and the LCD dis- play memory. When the BP is set as ²1², any data written into 40H~60H will effect the LCD display. When the BP is cleared to ²0², any data written into 40H~60H means to access the gen- eral purpose data memory. The LCD display memory can be read and written to only by indi- rect addressing mode using MP1. When data is written into the display data area, it is auto- matically read by the LCD driver which then generates the corresponding LCD driving sig- nals. To turn the display on or off, a ²1² or a ²0² is written to the corresponding bit of the display memory, respectively. The figure illustrates the mapping between the display memory and LCD pattern for the HT49C50. |
