This is an alternative pin configuration of PC5. 1.1.4 XTAL2 Output from the inverting amplifier of the oscillator. Alternative pin configuration of PC4. 1.1.5 RESET Reset input. A low level on this pin for longer than the minimum pulse length will generate a reset, even if the clock is not running and provided the reset pin has not been disabled. The minimum pulse length is given in Table 24-5 on page 231. Shorter pulses are not guaranteed to generate a reset. The reset pin can also be used as a (weak) I/O pin. 1.1.6 Port A (PA7:PA0) This is an 8-bit, bi-directional I/O port with internal pull-up resistors (selected for each bit). Output buffers have the following drive characteristics: ? PA7, PA4:PA0: Symmetrical, with standard sink and source capability ? PA6, PA5: Asymmetrical, with high sink and standard source capability As inputs, port pins that are externally pulled low will source current provided that pull-up resistors are activated. Port pins are tri-stated when a reset condition becomes active, even if the clock is not running. This port has alternate pin functions to serve special features of the device. See ?Alternate Functions of Port A? on page 62. 1.1.7 Port B (PB3:PB0) This is a 4-bit, bi-directional I/O port with internal pull-up resistors (selected for each bit).Output buffers have the following drive characteristics: ? PB3: Asymmetrical, with high sink and standard source capability ? PB2:PB0: Symmetrical, with standard sink and source capability As inputs, port pins that are externally pulled low will source current provided that pull-up resistors are activated. Port pins are tri-stated when a reset condition becomes active, even if the clock is not running. This port has alternate pin functions to serve special features of the device. See ?Alternate Functions of Port B? on page 65. 1.1.8 Port C (PC5:PC0) This is a 6-bit, bi-directional I/O port with internal pull-up resistors (selected for each bit).

This is an alternative pin configuration of PC5. 1.1.4 XTAL2 Output from the inverting amplifier of the oscillator. Alternative pin configuration of PC4. 1.1.5 RESET Reset input. A low level on this pin for longer than the minimum pulse length will generate a reset, even if the clock is not running and provided the reset pin has not been disabled. The minimum pulse length is given in Table 24-5 on page 231. Shorter pulses are not guaranteed to generate a reset. The reset pin can also be used as a (weak) I/O pin. 1.1.6 Port A (PA7:PA0) This is an 8-bit, bi-directional I/O port with internal pull-up resistors (selected for each bit). Output buffers have the following drive characteristics: ? PA7, PA4:PA0: Symmetrical, with standard sink and source capability ? PA6, PA5: Asymmetrical, with high sink and standard source capability As inputs, port pins that are externally pulled low will source current provided that pull-up resistors are activated. Port pins are tri-stated when a reset condition becomes active, even if the clock is not running. This port has alternate pin functions to serve special features of the device. See ?Alternate Functions of Port A? on page 62. 1.1.7 Port B (PB3:PB0) This is a 4-bit, bi-directional I/O port with internal pull-up resistors (selected for each bit).Output buffers have the following drive characteristics: ? PB3: Asymmetrical, with high sink and standard source capability ? PB2:PB0: Symmetrical, with standard sink and source capability As inputs, port pins that are externally pulled low will source current provided that pull-up resistors are activated. Port pins are tri-stated when a reset condition becomes active, even if the clock is not running. This port has alternate pin functions to serve special features of the device. See ?Alternate Functions of Port B? on page 65. 1.1.8 Port C (PC5:PC0) This is a 6-bit, bi-directional I/O port with internal pull-up resistors (selected for each bit).
