Depends on what you mean by a 16 bit counter. You could just use the
prescaler, but this limits count resolution, as you can't read the
prescaler. On parts other than the 5x series, the other way is to generate an
interrupt on the TMR0 rollover and keep a high-byte in software. It is
also possible to use a hybrid of these methods (i.e prescaler +
software count), depending on applications requirements.
