When you set the gain code of analog input channel n, you
should set the Multiplexer start & stop channel number to
channel n to prevent any unexpected errors. In fact BASE+4 bit
3 to bit 0, STA3 ~ STA0, act as a pointer to channel n’s address
in the SRAM when you program the A/D channel setting
(refer
to Section C.
5).
Caution!
We recommend you to set the same start and stop channel when writing to
the register BASE+2. Otherwise, if the A/D trigger source is on, the
multiplexer will continuously scan between channels and the range setting
may be set to an unexpected channel. Make sure the A/D trigger source is
turned off to avoid this kind of error.
The write-only registers of BASE +4 and BASE+5 control how the
multiplexers (Multiplexer) scan.
