Assume the value of the Stack pointer (SP) is 0x20000FF8 when the following code sequence starts execution (i.e., PC=000001000 ). The initial stack contents are given. Give the state of the stack (SP and contents) after executing of the PUSH instruction, as shown by arrow A. Give the state of the stack (SP and contents) while executing the instruction at memory location 00000100C as shown by the arrow B and the values stored in R0, R1, and R2
