h mode. Question 2 Multiple Choices- 20 points 1 All embedded systems or microcontrollers contain the components. a. CPU b. Memory device c. L/O Ports d. All of the above 2 The ARM Cortex-M4 MCU contains a. No memory b. 32-KB RAM c. 256-KB Flash Memory d.2-KB EEPROM - 3 The TM4C123GH6PM MCU memory map system includes a. 256-KB Flash Memory b. 32-KB SRAM c. 2-KB EEPROM and Internal ROM d. All of the above One prerequisite job of using any GPIO a. Configure the operational mode of the GPIO Port b. Configure the interrupt control registers on NVIC c. Enable the system clock to be connected to the selected GPIO Port d. Include and use the related peripheral driver library 4 Port is to 5 Although each GPIO control register is 32 bits, only theis used to provide a control byte function. a. Lowest 8 bits b. Highest 8 bits c. Lower 16 bits d. Highest 16 bits

Explanation / Answer

1. Microcontroller contains all of the above mentioned three parts.

A microcontroller  is a small computer on a single integrated circuit. In modern terminology, it is similar to, but less sophisticated than, a system on a chip or SoC; an SoC may include a microcontroller as one of its components. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals.

2. AR Cortex-M4 MCU contains three types of on Chip memory

So b,c,d are correct.

3.TM4C123GH6PM MCU Contains following memory devices on

So option d is the correct answer for this question

4. Ans is a. Configure the operational mode of the GPIO port.

Code for configuring GPIO

5. The real control bits are the lowest 8 bits for both registers, Pull - Up - Enable(PUE) byte and Pull - Down - ENable(PDE) byte.
