Question

Answer the following questions for MSP-432 processor with detailed calculations.

(a) How many different addresses are available for peripherals?

(b) How many different addresses are available for ports?

(c) Suppose an LED is connected to Port 2, Pin 5. Determine the memory address of Port 2.

(d) How many Bytes can be written in the ROM region? How many 32 bit words can be written in the ROM region?

Answer 1

(a) How many different addresses are available for peripherals?

--> Total allocated addresses : 0x4000_0000 – 0x5FFF_FFFF

--> Peripheral addresses : 0x4000_0000 – 0x400F_FFFF

--> Available address : 0x4010_0000 - 0x5FFF_FFFF

(b) How many different addresses are available for ports?

--> Each port registers has one fixed addresses for specific device.

(c) Suppose an LED is connected to Port 2, Pin 5. Determine the memory address of Port 2.

--> Memory address of Port 2 output = 0x4000_4C03  

(d) How many Bytes can be written in the ROM region? How many 32 bit words can be written in the ROM region?

--> ROM (code) addresses : 0x0000_0000–0x1FFF_FFFF

--> Total 8 bit bytes = 536870912 Bytes

--> Total 32 bit words = 134217728 Words
