Question

To select the value of the clock to be fosc/16, what are the appropriate values?

(a) SPI2X= 0, SPR1= 0, SPR0=1

(b) SPI2X= 0, SPR1= 1, SPR0=0

(c) SPI2X= 1, SPR1= 1, SPR0=0

(d) SPI2X= 0, SPR1= 1, SPR0=1

I have been asked this question during a job interview.

My query is from SPI Protocol topic in section AVR Microcontroller of Microcontroller

Answer 1

Right option is (a) SPI2X= 0, SPR1= 0, SPR0=1

For explanation: For obtaining this very clock frequency of fosc/16, we set the values of SPI2X= 0, SPR1=0 and SPR0=1.
