Functions
void	main (void)
void	initVarConfigPort (void)
void	runApplcn (void)
	PC is updated with the new pointer to execute loaded binary from the application flash program memory.
void	runStateMachine (void)
	function executes different states of the system. SYS_SND_ADDRS_RANGE - Send the PIC programmable start and end address of the program memory SYS_WAIT_FOR_START_CMND - The Start command triggers system to start the process and initializes buffer counter SYS_RCV_FIRMWARE_HEADER - Get the total packet count from the host and applcn start address SYS_CONFIG_FLASH - Erase application program area and update table pointer SYS_FIRMWARE_UPDATE - Receive and put the binary chunks in the flash memory SYS_RUN_APPLCN - Run the application
