5.8 I/O Characteristics for Ports PB0 to PB7 and PC0 to PC5

All parameters refer to GND (backplane) and are valid for T_amb = -40°C to +85°C, V_VS = 1.9-3.6V (3V application) and 2.4-5.5V (5V application) over all process tolerances, unless otherwise specified. Typical values are given at V_VS = 5V, T_amb = 25°C and for a typical process, unless otherwise specified. Crystal oscillator frequency f_XTO = 24.305 MHz. Standard Microchip EEPROM settings are used unless marked with ^*1.
