Question

What happens when 8 bits are transferred in the SPI?

(a) wait statement

(b) ready statement

(c) interrupt

(d) remains unchanged

This question was addressed to me by my college director while I was bunking the class.

I'm obligated to ask this question of Serial Port and Serial Peripheral Interface topic in section Basic Peripherals of Embedded Systems

Answer 1

Right answer is (c) interrupt

For explanation: The interrupts are locally generated when 8-bits are transferred so that the data can be read before the next byte is clocked through.
