Read Data from CG, DD, or SEG RAM
This instruction reads 8-bit binary data DDDDDDDD from CG, DD, or SEGRAM. CG, DD or SEGRAM
is selected by the previous specification of the address set instruction. If no address is specified, the first
data read will be invalid. When executing serial read instructions, the next address is normally read from
the next address. An address set instruction need not be executed just before this read instruction when
shifting the cursor by a cursor shift instruction (when reading from DDRAM). A cursor shift instruction is
the same as a set DDRAM address instruction.
After a read, the entry mode automatically increases or decreases the address by 1. However, a display
shift is not executed regardless of the entry mode.
Note:
The address counter (AC) is automatically incremented or decremented after write instructions to
CG, DD or SEGRAM. The RAM data selected by the AC cannot be read out at this time even if
read instructions are executed. Therefore, to read data correctly, execute either an address set
instruction or a cursor shift instruction (only with DDRAM), or alternatively, execute a
preliminary read instruction to ensure the address is correctly set up before accessing the data.
