Note 1: We call built-in RAM sequential access type LCD driver that use register to access to display RAM
Note 2: We call built-in RAM random access type LCD driver that is same method to access to SRAM. (e.g.,
LCDC1L, LCDC1H, LCDC2L, LCDC2H, LCDC3L, LCDC3H, LCDR1L, LCDR1H Register
without address. (e.g., T6B65A, T6C84 etc: mar/2000)
T6C23, T6K01 etc: mar/2000)

access type LCD driver.
These registers do not exist on TMP91C820A. These are image for instruction registers
Address as Table 3.14.3 is assigned to these registers, and the following chip enable pin
And, the area of these address is external area, so
Table 3.14.4 shows the address map in the case of controlling RAM built-in random
The explanation part of MMU circuit also explains this.
This setup is performed by LCDCTL <MMULCD>.
