Question 8
The Atmega2560 is an _________ bit chip.
A. 1
B. 2
C. 4
D. 8
View Answer
Ans : D
Explanation: The Atmega2560 is capable of processing 8 bits of data at a time and hence it has an 8-bit architecture. Other similar 8-bit processors include the Intel 8080 Processor which ran on a similar 8-bit architecture.
Question 9
Does the Atmega2560 have an index corner?
A. Yes
B. No
C. Can be yes or no
D. Can not say
View Answer
Ans : A
Explanation: The Atmega2560, like most other chips has an index corner which is used to identify the numbering of the pins when reading the pin configuration of the chip. Almost all chips have a similar index corner without which, numbering of the pins would be very difficult.
