There are 4 types of instructions:
In normal use, data transfer instructions are used most frequently. However, automatic
incrementing by 1 (or decrementing by 1) of internal RAM addresses after each data write
lessens the microcontroller program load. The display shift in particular can be performed
concurrently with display data write, enabling the designer to develop systems in minimum
time with maximum programming efficiency.
During internal operation, no instructions other than the ‘read busy flag’ and ‘read
address’ instructions will be executed. Because the busy flag is set to logic 1 while an
instruction is being executed, check to ensure it is logic 0 before sending the next
instruction or wait for the maximum instruction execution time, as given in
instruction sent while the busy flag is logic 1 will not be executed.
