<4-Bit Data Length Interface>
When executing a 4-bit operation, it is necessary to set respective functions on a program. After resetting, first write the
upper 4-bits of the function setting command to reset DL (DL = 0). Then this IC is set for the 4-bit data-length interface. Next
write the function setting command again for each upper 4-bits and lower 4-bits to complete the function command. Then
write commands to initialize this IC for 4-bit data-length interface. (See an example shown in the previous page.)
For the 4-bit data-length interface, the upper 4-bits are written first, followed by the lower 4-bits. The RS terminal for register
selection is used to distinguish instruction from data for a command. For the 4-bit data-length interface, do not change the
RS signal during the period when both the upper and lower 4-bits are written.
For the 4-bit data-length interface, open the lower 4-bit terminals of the data bus (DB3-DB0).
Notice that output short-circuit current will flow at READ phase if they are connected to the power supply (VDD or VSS)
