Does the Atmega328 have an index corner?
A. Yes
B. No
This question was addressed to me in an interview for internship.
This interesting question is from Microcontroller Specifications in portion AtMega Microcontroller Specifications of Arduino
The correct answer is A. Yes
Easiest explanation: The Atmega328, 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.
