STANDARD NAME:
7.5.9 ADDRESS COUNTER READ
This instruction reads the current 7-bit address from the AC on DB6-DB0 and the busy flag (BF)
bit (always 0) on DB7. DDRAM, CGRAM, and AC contents are not affected by this instruction.
Because the BF is always 0, the host never has to read the BF bit to determine if the modules are
busy before sending data or instructions. Therefore, data and instructions can be sent to the
module continuously according to the E, WR/, and SCK cycle times specified in section 3.7 AC
Timing Specifications. Due to this feature, the execution times for each instruction are not
specified.
7.5.10 DDRAM OR CGRAM WRITE
This instruction writes the 8-bit data byte on DB7-DB0 into the DDRAM or CGRAM location
addressed by the AC. The most recent DDRAM or CGRAM Address Set instruction determines
whether the write is to DDRAM or CGRAM. This instruction also increments or decrements the
AC and shifts the display according to the I/D and S bits set by the Entry Mode Set instruction.
7.5.11 DDRAM OR CGRAM READ
This instruction reads the 8-bit data byte from the DDRAM or CGRAM location addressed by
the AC on DB7-DB0. The most recent DDRAM or CGRAM Address Set instruction determines
whether the read is from DDRAM or CGRAM. This instruction also increments or decrements
the AC and shifts the display according to the I/D and S bits set by the Entry Mode Set
instruction. Before sending this instruction, a DDRAM or CGRAM Address Set instruction
should be executed to set the AC to the desired DDRAM or CGRAM address to be read.
