Ground.
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.
Port B also serves the functions of various special features of the ATmega16/32/64/M1/C1 as
listed on
Port C is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit).
The Port C 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.
Port C also serves the functions of special features of the ATmega16/32/64/M1/C1 as listed on
page
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.
Port D also serves the functions of various special features of the ATmega16/32/64/M1/C1 as
listed on
Port E is an 3-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 are externally pulled low will source current if the
pull-up resistors are activated. The Port E pins are tri-stated when a reset condition becomes
active, even if the clock is not running.
If the RSTDISBL Fuse is programmed, PE0 is used as an I/O pin. Note that the electrical char-
acteristics of PE0 differ from those of the other pins of Port E.
If the RSTDISBL Fuse is unprogrammed, PE0 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 run-
ning. The minimum pulse length is given in
guaranteed to generate a Reset.
