3.6 CHARACTER DISPLAY POSITION CONTROL COMMAND
and one of 32 steps in three-line units for the vertical direction (this command is a 2-byte command, requiring 16 bits for
each command even when continuously input).
(LSB)
D0
V3
This command specifies the character display start position with one of 32 steps in 12-dot units for the horizontal direction,
(1) For MSB-first transfer (Command bits are input starting from the MSB (D15).)
(2) For LSB-first transfer (Command bits are input starting from the LSB (D0). The function of each bit is the same as
(MSB)
D15
that for MSB-first transfer.)
