PD6461, 6462
3.8 OUTPUT PIN CONTROL COMMAND
This command distributes character signals to the V
C1
and V
C2
channels (this command is a 2-byte command, requiring
16 bits for each command, even when continuously input). The
μ
PD6461, 6462 support a mask option for selecting one
of three formats for the output distribution format for the V
C1
and V
C2
channels.
(1) For MSB-first transfer (Command bits are input starting from the MSB (D15).)

Row specification bits
Function
Specifies row 0.
Specifies row 1.
Specifies row 11.
Other values are invalid.
Option A
Output pin control bits
Output from each pin
V
C1
: Outputs a specified row. V
C2
: Fixed to low level.
V
C1
: Fixed to low level. V
C2
: Outputs a specified row.
Option B
Output pin control bits
Output from each pin
V
C1
: Outputs all rows. V
C2
: Fixed to low level.
V
C1
: Outputs all rows. V
C2
: Outputs a specified row.
Option C
Output pin control bits
Output from each pin
V
C1
: Outputs columns 0 to 23. V
C2
: Fixed to low level.
V
C1
: Outputs columns 0 to 11. V
C2
: Outputs columns 12 to 23.
V
C1
: Outputs columns 12 to 23. V
C2
: Outputs columns 0 to 11.
V
C1
: Fixed to low level. V
C2
: Outputs columns 0 to 23.
(2) For LSB-first transfer (Command bits are input starting from the LSB (D0). The function of each bit is the same as
that for MSB-first transfer.)
Row specification bits
Output distribution to the V
C1
and V
C2
pins is specified for each row (or for 12 columns). These bits are used to
specify the row.
Output pin control bits
These bits are used to distribute character output signals to the V
C1
and V
C2
pins depending on whether option
A, B, or C has been selected by specifying a mask option (the corresponding blanking signals are output likewise).
