ANDA Instruction is used to clear the bits
ORAB instruction is used to set the bits.
A- Using either “ANDA” or “ORAA” instructions, write an HCS12 code to clear bits 0, 2,5,...
S4.1) Write C code to set all odd bits (b1, 63, b5, b7) in the uint_8 variable PORT. All other bits should not be changed. S4.2) Write C code to clear bits b3, 64, and b5 in the uint_8 variable PORT. All other bits should not be changed. S4.3) Write C code to toggle all even bits in the uint_8 variable PORT. All other bits should not be changed.
Use HCS12 assembly language only - not C code Using CodeWarrior to create a new project that uses assembly language. Write an assembly program that turns on the red LED at the beginning. It switches to off 2 seconds later and switches back to on after three more seconds. (That is, it stays on for 2 seconds and off for 3 seconds.) This switching process lasts forever. Use a loop (or nested loops) for each of the 2/3-second delay where...
2.Write code that jumps to label Ll if either bit 4, 5, or 6 is set in the BL register (10')
Implement the following statements using MS430 assembly instructions. You may use more than one, but you should minimize the number of instructions required. You can use both native and emulated instructions. Use hex notation for all numbers 1. (a) Move the word located in register R14 to R15 (b) Increment the word in R6 by 2. (c) Perform a bitwise ANDing of the word located at address 0x0240 with the datum in R15, placing the results in R15. (d) Rotate...
Write an Verilog code for a 8-bit subtractor (Bits are in 1's complement) using the following: 1. 5-bit parallel adder 2. 3-bit parallel adder The condition are as follows: 1. The Most Significant bits of the subtractor must be given to the 5-bit parallel adder. 2, The Least Significant bits of the subtractor must be given to the 3-bit parallel adder. 3. The input A will be assign to the switches with the least significant bit A[0] linked to SW0....
Write assembly instructions to set Bit 3 of variable foo without changing other bits. Any quick response to this would be highly appreciated.
A)What is the maximum delay that can generated by an 8 bit Timer with a prescale divider value of 0 and a system clock frequency of 16 MHz? B) In the HCS12, port T is a bidirectional port. Write a short segment of code (C and Assembly) that illustrates how to initialize port T so that bits 7-4 may be used as outputs and bits 3-0 may be used as inputs: C)If you are using an output compare with interrupts...
Application Problem: Answer the following questions at the bottom of the worksheet: You are configuring a microcontroller (uC) to sample a signal connected to an input pin. Part of the initial setup requires that you clear (turn off) bits #17 and #2 in a 32-bit register, while leaving all other bits unchanged. To work with specific bits, we typically use a second number, called a mask, which has the bit positions we need to alter set to 1, and all...
1a. Write the 32 bits that represent the following R type instructions: add $7, $5, $3 b. Write the 32 bits that represent the following I type instructions: add $7, $5, $3 c. What is the largest unsigned value that can be stored in the imm within an i type instruction?
