ATmega256/128/64RFR2
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 provides functions of various special features of the
ATmega256/128/64RFR2.
3.2.10 Port F (PF7...PF0)
Port F is an 8-bit bi-directional I/O port with 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.
Port F also provides functions of various special features of the
ATmega256/128/64RFR2.
3.2.11 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 buffers have symmetrical drive characteristics with both high
sink and source capability. However the driver strength of PG3 and PG4 is reduced
compared to the other port pins. The output voltage drop (V
OH
, V
OL
) is higher while the
leakage current is smaller. 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 provides functions of various special features of the
ATmega256/128/64RFR2.
3.2.12 AVSS_RFP
AVSS_RFP is a dedicated ground pin for the bi-directional, differential RF I/O port.
3.2.13 AVSS_RFN
AVSS_RFN is a dedicated ground pin for the bi-directional, differential RF I/O port.
3.2.14 RFP
RFP is the positive terminal for the bi-directional, differential RF I/O port.
3.2.15 RFN
RFN is the negative terminal for the bi-directional, differential RF I/O port.
3.2.16 RSTN
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.
3.2.17 RSTON
Reset output. A low level on this pin indicates a reset initiated by the internal reset
sources or the pin RSTN.
3.2.18 XTAL1
Input to the inverting 16MHz crystal oscillator amplifier. In general a crystal between
XTAL1 and XTAL2 provides the 16MHz reference clock of the radio transceiver.
3.2.19 XTAL2
Output of the inverting 16MHz crystal oscillator amplifier.
3.2.20 AREF
Reference voltage output of the A/D Converter. In general this pin is left open.
3.2.21 TST
Programming and test mode enable pin. If pin TST is not used pull it to low.
