1. What is the purpose of a makefile?
-A makefile is used to collect the individual commands to compile code.
2. Draw the five-step flowchart that takes main.c and creates main.hex in the compilation process.
-main.c->Preprocessor->Complier->main.s->Assembler->main.o->Linker->main.elf->Hex2bin->main.hex
3. Write the value of PORTD in 16-bit (4-digit) hex when pins 0,1,4,5 are HIGH and the rest are LOW.
-0x33
4. Rewrite the following lines with one line of code, each using only one of LATACLR, LATASET, and LATAINV. Give the values in 16-bit (4-digit) hex.
	A. LATAbits.LATA4 = 1;
	-LATASET = 0x0010;
	B. LATAbits.LATA5 = !LATAbits.LATA5;
	-LATAINV = 0x0020;
	C. LATA &= 0b1111 1111 0011 0101;  (spaces added for readability; they're not really there)
	-LATACLR = 0x00CA;
5. What do the 3 most significant bits in a virtual address signify?
-Wether the address is cacheable.
6. Which two of the following four properties are set by the Device Configuration Registers?
	Primary oscillator mode, Peripheral bus clock divisor
