Set DDRAM Address
Set DDRAM address sets the DDRAM address binary AAAAAAA into the address counter.
Data is then written to or read from the MPU for DDRAM.
However, when N is 0 (1-line display), AAAAAAA can be 00H to 4FH. When N is 1 (2-line display),
AAAAAAA can be 00H to 27H for the first line, and 40H to 67H for the second line.
Read Busy Flag and Address
Read busy flag and address reads the busy flag (BF) indicating that the system is now internally operating
on a previously received instruction. If BF is 1, the internal operation is in progress. The next instruction
will not be accepted until BF is reset to 0. Check the BF status before the next write operation. At the same
time, the value of the address counter in binary AAAAAAA is read out. This address counter is used by
both CG and DDRAM addresses, and its value is determined by the previous instruction. The address
contents are the same as for instructions set CGRAM address and set DDRAM address.
