Figure 2. Device selection for analog-to-digital conversion
If you are using the analog trimmer, select the installed ST7 device using jumper W6 as
shown in
Figure 2 . This ties the analog trimmer to the PA0 I/O port of the ST7262xxx
devices and to the PB0 port of the ST7263Bxx devices. Any other analog input pin on the
microcontroller can be used by removing the W6 jumper and wiring the center pin of W6 to
the analog input.
The W7 jumper can be used to connect or disconnect an external 12V charge pump in case
you want to program the Flash.
