ST7522

See the Table of ST7522 instructions. The ST7522 series identifies a data bus using a combination of A0 and R/W (RD
signals. As the MPU translates a command in the internal timing only (independent from the external clock), its speed
is very high. The busy check is usually not required.
This command specifies the page address that corresponds to the low address of the display data RAM when it is accessed
by the MPU. Any bit of the display data RAM can be accessed when its page address and column address are specified.
The display status is not changed even when the page address is changed.
