Suppose that an 8-bit microcontroller has a 16-bit stack pointer and uses

Suppose that an 8-bit microcontroller has a 16-bit stack pointer and uses a 16-bit register to access the stack from the top. Assume that initially the stack pointer and the 16-bit register contain 20C016 and 020516, respectively. After the PUSH operation (a) What are the contents of the stack pointer? (b) What are the contents of memory locations 20BE16 and 20BF16?
