Built-in RAM Type LCD driver Mode

3.14.6.1 Description of Operation

Data transmission to the LCD driver is executed by a transmit instruction from the

After setting operation mode of to the control register, when a CPU transmit

instruction is executed the LCDC outputs a chip select signal to the LCD driver

connected externally by the control pin (LCP0...). Therefore control of data

transmission numbers corresponding to LCD size is controlled by CPU instruction.

There are 2 kinds of LCD driver address in this case, which are selected by the

LCDCTL<MMULCD> register.

3.14.6.2 Random Access Type

This corresponds to address direct writing type LCD driver when <MMULCD> = "1".

The transmission address can also assign the memory area 3C0000H − 3FFFFF, the

four areas each being 64 Kbytes.

Interface and access timing are the same as for normal memory. Refer to the

memory access timing section.
