ATmega165A/PA/325A/PA/3250A/PA/645A/P/6450A/P [DATASHEET]
8285E–AVR–02/2013
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 Atmel
ATmega165A/165PA/325A/325PA/3250A/3250PA/645A/645P/6450A/6450P as listed on ”Alternate functions of
2.3.6
Port D (PD7:PD0)
Port D is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port D output buf-
fers 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
ATmega165A/165PA/325A/325PA/3250A/3250PA/645A/645P/6450A/6450P as listed on ”Alternate functions of
2.3.7
Port E (PE7:PE0)
Port E is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port E output buf-
fers 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.
Port E also serves the functions of various special features of the
ATmega165A/165PA/325A/325PA/3250A/3250PA/645A/645P/6450A/6450P as listed on ”Alternate functions of
2.3.8
Port F (PF7:PF0)
Port F serves as the analog inputs to the A/D Converter.
Port F also serves as an 8-bit bi-directional I/O port, if the A/D Converter is not used. Port pins can provide internal
pull-up resistors (selected for each bit). The Port F output buffers have symmetrical drive characteristics with both
high sink and source capability. As inputs, Port F pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port F pins are tri-stated when a reset condition becomes active, even if the clock is not
running. If the JTAG interface is enabled, the pull-up resistors on pins PF7(TDI), PF5(TMS), and PF4(TCK) will be
activated even if a reset occurs.
Port F also serves the functions of the JTAG interface, see ”Alternate functions of Port F” on page 73.
2.3.9
Port G (PG5:PG0)
Port G is a 6-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port G output buf-
fers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port G pins that are
externally pulled low will source current if the pull-up resistors are activated. The Port G pins are tri-stated when a
reset condition becomes active, even if the clock is not running.
Port G also serves the functions of various special features of the
ATmega165A/165PA/325A/325PA/3250A/3250PA/645A/645P/6450A/6450P as listed on page 75.
2.3.10
Port H (PH7:PH0)
Port H is a 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port H output buf-
fers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port H pins that are
externally pulled low will source current if the pull-up resistors are activated. The Port H pins are tri-stated when a
reset condition becomes active, even if the clock is not running.
Port H also serves the functions of various special features of the ATmega3250A/3250PA/6450A/6450P as listed
