Question
The MSP430F20x is a microcontroller with 64 KiB of address space divided between code memory (flash), RAM memory, and input/output peripherals. It has 2,048 Bytes
The MSP430F20x is a microcontroller with 64 KiB of address space divided between code memory (flash), RAM memory, and input/output peripherals. It has 2,048 Bytes of RAM memory starting at the address 0x0200, and 256 Bytes of address space reserved for special purpose registers and 8-bit input/output peripherals (starting at the address 0x0000) followed by 256 Bytes reserved for 16-bit input/output peripherals. The flash memory of 16 KiB resides at the top of address space (highest addresses in the address space).
C. Determine the address map by filling in the following table.
Address | Byte Address (hexadecimal) | Sections in address space |
Last Flash Address | Flash Memory | |
First Flash Address | Flash Memory | |
Last RAM address | RAM Memory | |
First RAM address | RAM Memory | |
Last I/O address (16-bit per.) | I/O address space | |
First I/O address (16-bit per.) | ||
Last I/O address (8-bit per.) | I/O address space | |
First I/O address (8-bit per.) |
D. What is the maximum stack size in the MSP430Fx described above? What should be the initial value of SP? Using RTL notation, describe operations carried out to execute the following two instructions: PUSH R9 and POP R9. Stack size: __________________Bytes Initial stack pointer: SP = PUSH R9: POP R9:
