2.1.3
Port B (PB7:0) XTAL1/XTAL2/TOSC1/TOSC2
Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port B output
buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port B pins that
are externally pulled low will source current if the pull-up resistors are activated. The Port B pins are tri-stated when
a reset condition becomes active, even if the clock is not running.
Depending on the clock selection fuse settings, PB6 can be used as input to the inverting Oscillator amplifier and
input to the internal clock operating circuit.
Depending on the clock selection fuse settings, PB7 can be used as output from the inverting Oscillator amplifier.
If the Internal Calibrated RC Oscillator is used as chip clock source, PB7:6 is used as TOSC2:1 input for the
Asynchronous Timer/Counter2 if the AS2 bit in ASSR is set.
The various special features of Port B are elaborated in ”Alternate Functions of Port B” on page 82 and ”System
Clock and Clock Options” on page 29.
2.1.4
Port C (PC5:0)
Port C is a 7-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The PC5...0 output
buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port C pins that
are externally pulled low will source current if the pull-up resistors are activated. The Port C pins are tri-stated when
a reset condition becomes active, even if the clock is not running.
2.1.5
PC6/RESET
If the RSTDISBL Fuse is programmed, PC6 is used as an I/O pin. Note that the electrical characteristics of PC6
differ from those of the other pins of Port C.
If the RSTDISBL Fuse is unprogrammed, PC6 is used as a 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. Shorter pulses are not guaranteed to
generate a Reset.
The various special features of Port C are elaborated in ”Alternate Functions of Port C” on page 85.
2.1.6
Port D (PD7:0)
Port D is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port D output
buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port D pins that
are externally pulled low will source current if the pull-up resistors are activated. The Port D pins are tri-stated when
a reset condition becomes active, even if the clock is not running.
The various special features of Port D are elaborated in ”Alternate Functions of Port D” on page 87.
2.1.7
Port E(PE3:0)
Port E is an 4-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port E output
buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port E pins that
