Overflow will never occur in the case of the a addition of t

Overflow will never occur in the case of the a. addition of two positive binary numbers. b. addition of a positive and a negative binary number. c. addition of any two fixed-point binary numbers. Compared to a conventional microprocessor, a microcontroller is a. a small computer system on a chip. b. more powerful in the computation. c. more effective for digital signal processing. In the execution of the following assembly instruction of ARM Cortex-M4 processors: ADD R0, R2, R3 a. one operand is read from system memory b. an overflow occurs. c. the condition code flags are not updated. The addressing mode of the following assembly instruction of an ARM Cortex-M4 STR R2, [R0] a. is register addressing mode b. is direct addressing mode. c. is indirect addressing mode.

Solution

4 -> b

Explaination:

5-> a

Explaination:

Microcontroller has a CPU, in addition with a fixed amount of RAM, ROM and other peripherals all embedded on a single chip. At times it is also termed as a mini computer or a computer on a single chip

6-> a

Explaination:

Where in, operand 1 has to be read from register and operand 2 can be a register, shifted register, or an immediate value.

7-> c

Explaination:

In this mode  the base registers are coded within square brackets for memory references
