I/Os stable. Negative injection current on the I/Os close to the inputs may reduce the accuracy. In particular care must be
taken to avoid switching on I/Os close to the inputs when the comparator is in use. This phenomenon is even more critical
when a big external serial resistor is added on the inputs.
