Pin Descriptions
1.1.1
VCC
Digital supply voltage.
1.1.2
GND
Ground.
1.1.3
Port A (PA2..PA0)
Port A is a 3-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port A output buffers have symmetrical drive characteristics with both high sink and source
capability, except PA2 which has the RESET capability. To use pin PA2 as I/O pin, instead of
RESET pin, program (“0”) RSTDISBL fuse. As inputs, Port A pins that are externally pulled low
will source current if the pull-up resistors are activated. The Port A pins are tri-stated when a
reset condition becomes active, even if the clock is not running.
Port A also serves the functions of various special features of the ATtiny2313A/4313 as listed on
page 61.
1.1.4
Port B (PB7..PB0)
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 ATtiny2313A/4313 as listed on
page 62.
1.1.5
Port D (PD6..PD0)
Port D is a 7-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 ATtiny2313A/4313 as listed on
page 66.
1.1.6
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 that the reset pin has not been disabled. The
minimum pulse length is given in Table 22-3 on page 201. Shorter pulses are not guaranteed to
generate a reset. The Reset Input is an alternate function for PA2 and dW.
The reset pin can also be used as a (weak) I/O pin.
1.1.7
XTAL1
Input to the inverting Oscillator amplifier and input to the internal clock operating circuit. XTAL1
is an alternate function for PA0.
