(2) Example of output to the channel 1
Internal data is output to channel 1 by setting it in an 8-bit D/A
converter.
The D/A converter output ranges from -5 to +5 V, depending on a set
value of internal data. See the table below.

(whether there is offset)
Output on channel 1
00000000 (0) 0 -5V
11111111 (255) 0 +4.96V
10000000 (-128) 1 -5V
00000000 (0) 1 0V
01111111 ( 127) 1 +4.96V
Example 1 Data set
When the number of digits to shift data (d-06)=0 and when no offset is
provided (d-08=0): The last eight bits of data (BIT07 to BIT00) is set in
the D/A converter of the LM terminal.
BIT07 BIT00BIT01
Set in the D/A converter for channel 1 output
BIT06 BIT05 BIT04 BIT03 BIT02
Example 2 Shifting data left
When the number of digits to shift data (d-06)=3, shift direction is right
(d-07=1), and no offset is provided (d-08=0): Data in BIT14 to BIT00
and the last three bits of data (=0) are set in the D/A converter.
BIT04 00
Set in the D/A converter for channel 1 output
BIT03 BIT02 BIT01 BIT00 0
Example 3 Shifting data right
When the number of digits to shift data (d-06)=10, shift direction is
right (d-07=1), and no offset is provided (d-08=0): Data in BIT17 to
BIT10 is set in the D/A converter.
