The following table are host interface examples for various UC1602I operations.
Step sequences starting with the same number (such as 2a, 2b, 2c, …) can be rearranged without affecting
the result. Some optional steps have mutual dependencies. Such mutually-dependent optional steps need to
be elected or skipped together as a group.
C/D

BZ, OM The status of these flags “ during ” the operation of the command.
(Opt.)
P
The only “ required ” command to initialize UC1602I is Set Display ON . However, many other commands
(such as Set APO = 0/1, Set LCD Mapping ) and any of the NOP bit patterns can be used for maximum
software compatibility with other industry leading LCD controller-drivers.
The following command sequence can be performed in parallel 8-bit, I
Example 1: Use System Reset command.

The type of the interface cycle. Depending on the interface type (parallel or serial).
This may be external pin (parallel and serial 8-bit), part of the bit stream (serial 9-bit write) or the
internal flag (serial 9-bit read).
The direction of data flow of the cycle. It can be either Write (0) or Read (1).
Optional item.
Example 1 does not require the use of RST pin and therefore is more appropriate for applications
where compact connector size is critical.
