The 2-byte continuous command is used to write characters to video RAM. When continuously writing characters for
which the specifications for the color, blinking, reversing, and V
C2
channel are the same, transfer the first byte of the first
command then continuously transfer only the second bytes (character pattern addresses) of the commands.
When changing any part of the first byte, end continuous input (by setting the CS signal to high or transferring the end
code for second-byte continuous input) then transfer the newly modified first byte.
