The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, SPI ports and interruptsystem to continue functioning. The Power-down mode saves the register contents but freezesthe Oscillator, disabling all other chip functions until the next interrupt or Hardware Reset. TheADC Noise Reduction mode stops the CPU and all I/O modules except ADC, to minimize switch-ing noise during ADC conversions. In Standby mode, the Crystal/Resonator Oscillator is runningwhile the rest of the device is sleeping. This allows very fast start-up combined with low power consumption. The device is manufactured...

4.2.5Port D (PD7..PD0) Port D is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). ThePort D output buffers have symmetrical drive characteristics with both high sink and sourcecapability. As inputs, Port D pins that are externally pulled low will source current if the pull-upresistors 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 AT90PWM216/316 as listedon page 73. 4.2.6Port E (PE2..0) RESET/ XTAL1/XTAL2 Port E is...

The fast-access Register File contains 32 x 8-bit general purpose working registers with a singleclock cycle access time. This allows single-cycle Arithmetic Logic Unit (ALU) operation. In a typ-ical ALU operation, two operands are output from the Register File, the operation is executed,and the result is stored back in the Register File in one clock cycle.Six of the 32 registers can be used as three 16-bit indirect address register pointers for DataSpace addressing ֖ enabling efficient address calculations. One of the these address pointers can also be used as an address pointer for look up...
