3.5 BUSY Period for Command Input
The BUSY period for command input is distinguished depending on whether a 1-byte, 2-byte, or 2-byte
contiguous command is used.
When inputting 2-byte contiguous command, there are two timings as shown below, (1) Not transferring 2-
byte contiguous command in Vsync period with detecting Vsync and (2) Transferring 2-byte contiguous
command in Vsync period without detecting Vsync.
When inputting commands in succession, observe the following timing:
