My arm based microcontroller has 32 one bit sized gpio ports in a port group. i can use these 32gpio ports for connecting to a port of any width between 1 and 32 (as long as pin placement matches).the port group has a 32 bit dir register and each one bit port in the port group has a corresponding dirregister bit in the 32 bit dir register. the dir register is implemented at address 0x41004400 (for port1).consider the two cases - first when i use all 32 ports as a single 32 bit wide port and the second casewhen i use all 32 bit ports as individual 1 bit wide ports. for both these cases to work, my dir registermust be word-accessible as well as bit accessible. write a program to show how you will provide bothword as well as bitwise access to the dir register. your program must use an appropriate data structurefor the register and allow it to be accessed either in bit-wide accesses or in a word-wide access. for output-a. store 0 in the dir register instance with a word-wise access. b. access it using bit-wise access to set bit 3.c. access it using word-wise access to print the value of the 32 bit register. d. access it using word-wise access to set bit 7 without changing other bits. e. access it using bit-wise access to print the value of bit 7.
