Detailed explanation-1: -Explanation: For I/O programming of the ports in AVR microcontrollers, there are basically three main registers. They are PORT, PIN, DDR, so all of the mentioned is the right option.
Detailed explanation-2: -Each port in AVR microcontroller has three I/O registers associated with it. They are designated as PORTx, DDRx and PINx.
Detailed explanation-3: -6. In AVR, which of the following registers are used for SPI? Explanation: In AVR, SPSR(SPI Status Register), SPCR(SPI Control Register) and SPDR(SPI Data Register) are used for programming the SPI module.
Detailed explanation-4: -There are 32 general-purpose 8-bit registers, R0–R31. All arithmetic and logic operations operate on those registers; only load and store instructions access RAM.
Detailed explanation-5: -There are three I/O registers associated with each port. These are as follows: Data register PORTx. Data direction register DDRx.
