Which of the following indicates the type of operation that the master requests?

(a) address value

(b) initial value

(c) terminal count

(d) first byte

The question was posed to me in a national level competition.

This intriguing question comes from I2C-II in portion Basic Peripherals of Embedded Systems

Best answer
Correct choice is (a) address value

To explain I would say: The address value helps the master to select the device and indicates what operation should be taken. If the 8th bit is logic one, read operation takes out and if it is logic zero, write operation takes out.
