Tо exаctly denоte hоw the microcontroller is to be electricаlly connected to the externаl slave device, match each of the signal labels "A", "B", "C", and "D", depicted in Fig. 2, to either [1] one of the signals labels "E", "F", or "G", also depicted Fig. 2, or [2] the label "N/C", which is to denote that no connection should be made. (Note that the internal signal label "PE2" for the microcontroller is not a typo.)   Fig. 2. Hardware block diagram.
