1.1 Pin Descriptions 1.1.1 VCC Supply voltage. 1.1.2 GND Ground. 1.1.3 XTAL1 Input to the inverting amplifier of the oscillator and the internal clock circuit. This is an alternative pin configuration of PC5. 1.1.4 XTAL2 Output from the inverting amplifier of the oscillator. Alternative pin configuration of PC4. 1.1.5 RESET Reset input.

• PC5:PC1: Symmetrical, with standard sink and source capability • PC0: Asymmetrical, with high sink and standard source capability As inputs, port pins that are externally pulled low will source current provided that pull-up resistors are activated. Port pins are tri-stated when a reset condition becomes active, even if the clock is not running. This port has alternate pin functions to serve special features of the device. See “Alternate Functions of Port C” on page 67. 2.

The AVR core combines a rich instruction set with 32 general purpose working registers. All 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in a single instruction, executed in one clock cycle. The resulting architecture is compact and code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.

C • Port Pin Should Not Be Used As Input When ULP Oscillator Is Disabled 1. Port Pin Should Not Be Used As Input When ULP Oscillator Is Disabled Port pin PB3 is not guaranteed to perform as a reliable input when the Ultra Low Power (ULP) oscillator is not running. In addition, the pin is pulled down internally when ULP oscillator is disabled.
