9.1.4 Set Page Address
This instruction sets the Page Address of display data RAM from the microprocessor into the page address register. Any
RAM data bit can be accessed when its Page Address and column address are specified. Along with the column address,
the Page Address defines the address of the display RAM to write display data. Changing the Page Address doesn’t affect
the display status. Set Page Address instruction can not be used to set the page address to “16”. Use ICON control register
ON/OFF instruction to set the page address to “16”.
9.1.5 & 9.1.6 Set Column Address
These instructions set the specified column address of DDRAM into the internal Column Address register. The internal
Column Address register points to the address of DDRAM for accessing display data. The Column Addresses register is
automatically increased by 1 when the microprocessor accesses the display data in DDRAM.
