Assume that the content of A is $A7 and that the content of B is $20. Find the contents of A and B after the MUL instruction is executed. [Hint: The MUL instruction assumes that the contents of A and B are unsigned integer values.]
Which of the following is incorrect? Select one or more: In AVR, the data memory includes 32 general registers, 64 I/O registers and SRAM. In AVR, both program and SRAM memories have 8-bit data width. The AVR can read both an instruction and data from memory at the same time. The more registers we have for a CPU, the slower processing we can.
