I was reading 17xx series` data sheet, and I had trouble understanding a specific explanation given for a major number of pins:
5 V tolerant pad providing digital I/O with TTL levels and hysteresis and analog output function. When configured as the DAC output, digital section of the pad is disabled. This pin is pulled up to a voltage level of 2.3 V to 2.6 V."
Now I understand what TTL and hysteresis are, so no need to explain them for me. I`m not certain what the last sentence means. Does it mean when those pins are configured with pull-up resistors the voltage level changes to "2.3 V to 2.6 V"?
