Product data sheet
10.1 Data register
10.2 Instruction register
The RS bit determines which register will be accessed and the R/W bit indicates if it is a
read or a write operation (see
Table 10.
[1]
[2]
Details of the instructions are explained in subsequent sections.
The data register temporarily stores data to be read from the DDRAM and CGRAM. Prior
to being read by the Read_data instruction, data from the DDRAM or CGRAM,
corresponding to the address in the instruction register, is written to the data register.
The instruction register stores instruction codes such as Clear_display, Curs_disp_shift,
and address information for the Display Data RAM (DDRAM) and Character Generator
RAM (CGRAM). The instruction register can be written to but not read from by the system
controller.
The instruction register is sectioned into basic, standard and extended instructions. Bit
H = 1 of the Function_set instruction (see
instruction set mode.
Symbol

R/W
There is only write access to the instruction register, but read access to the busy flag (BF) and the address
counter (AC) of the BF_AC instruction (see
Write and read access.
