1.1. Pin Descriptions

Digital supply voltage.
1.1.2. GND
Ground.
1.1.3. Port B (PB[3:0])
This is a 4-bit, bi-directional I/O port with internal pull-up resistors, individually selectable for each bit. The
output buffers have symmetrical drive characteristics, with both high sink and source capability. As inputs,
the port pins that are externally pulled low will source current if pull-up resistors are activated. Port pins
are tri-stated when a reset condition becomes active, even if the clock is not running.
1.1.4. 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 the reset pin has not been disabled. The minimum pulse length is
given in System and Reset Characteristics of Electrical Characteristics. Shorter pulses are not
guaranteed to generate a reset.
The reset pin can also be used as a (weak) I/O pin.
