Question $2(5$ points$)$

The MSP$430$X family $($X stands for eXtended$)$ can handle a larger amount of memory since it has a $20-$bit wide address bus. This family of processors is built based on a von Neumann architecture and is byte$-$addressed as well. The data bus is $16$ bits wide.

$($a$)$ What is the maximum number of bytes that can be addressed? Enter a decimal value.

$($b$)$ True or False: The MSP$430$X family is based on a $20-$bit architecture.
