3.8 OUTPUT PIN CONTROL COMMAND
16 bits for each command, even when continuously input). The PD6461, 6462 support a mask option for selecting one
of three formats for the output distribution format for the V
(MSB)
This command distributes character signals to the V
(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
• Row specification bits
• Output pin control bits
