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.
