Question

How can both single byte and the double byte address slave use the same bus?

(a) extended memory

(b) extended address

(c) peripheral count

(d) slave bus

The question was asked by my school principal while I was bunking the class.

The above asked question is from I2C-II topic in section Basic Peripherals of Embedded Systems

Answer 1

Correct choice is (b) extended address

To elaborate: For providing more addressing, an extended address is developed which possesses two bytes in which the first byte uses a special code to distinguish it from a single byte address so that the single byte and double byte address slaves can use a shared bus.
