1 1 This configuration is used to cause an incre-
ment or a decrement of a DAC. Right or
left DAC and inc/dec are selected by
D0 to D3 value.
A2, A3 DECODING (Channel Selection)
Every time a command or a initialization is sent to
the L6280, a channel must be selected. This is
done via A2 and A3 according to the table.
