NHD-2.7-12864WDY3 Details

The recommended power-on sequence is to apply VCC first, followed by VLOGIC, and then enable the display by setting the EN pin high.
The display must be initialized by sending a series of commands in a specific order, including the Function Set command, the Display Control command, and the Clear Display command.
The maximum frequency for the clock signal is 4 MHz.
Yes, a level shifter can be used to convert the 5V logic to 3.3V, but ensure that the level shifter is capable of handling the required data transfer rate.
The busy flag (BF) should be polled to ensure that the display is not busy before sending new commands or data. The BF is set high when the display is busy and cleared when the display is ready to accept new data.
