Notes:
1. It is mandatory to connect all available V
pins to ground.
2. When the pin is configured as analog input, positive and negative current injections are not allowed.
3. PCOR not implemented but p-transistor always active in output mode (refer to

Caution: During normal operation
this pin must be pulled- up, inter-
nally or externally (external pull-up
of 10k mandatory in noisy environ-
ment). This is to avoid entering ICC
mode unexpectedly during a reset.
In the application, even if the pin is
configured as output, any reset will
put it back in input pull-up
