4. OPERATING PRINCIPLES & METHODES
4.1 Register
The LCD Controller has two 8-bit registers, the Instruction register (IR) and the data
register (DR).
The IR is a write only register to store instruction codes like Display Clear or Cursor Shift
as well as addresses for the Display Data RAM (DD RAM) or the Character Generator
RAM (CG RAM).
The DR is a read/write register used for temporarily storing data to be read/written to/from
the DD RAM or CG RAM. Data written into the DR is automatically written into DD RAM or
CG RAM by an internal operation of the display controller.
The DR is also used to store data when reading out data from DD RAM or CG RAM.
When address information is written into IR, data is read out from DD RAM or CG RAM to
DR by an internal operation. Data transfer is then completed by reading the DR.
After performing a read from the DR, data in the DD RAM or CG RAM at the next address
is sent to the DR for the next read cycle. The register select (RS) signal determines which
of these two registers is selected.
