	Instructions not discussed here
	Access designator
	Using some of the new instructions
18 Series I/O ports
Dealing with 2 and 3-byte registers designated by a label
18 Series data memory
	Data memory map - PIC18F1220
	Banking and the access bank
		Bank select register (BSR)
	Data memory table operations - indexed addressing
		LFSR Instruction
	MOVFF instruction
18 Series special function registers - overview
18 Series program memory table read operations
	Creating tables
	Identifying tables
	Pointing
		Example - create a table and read data in the first location
		Example - create a table and read data in the third location
			by incrementing the table pointer
		Example - create a table and read data in the fourth location
			by adding the offset to the table pointer
		Example - create a table and read data in the fifth location
			using a loop with a counter
		Example - create an ASCII text message in a table - use counter
			    to detect end
			Schematic for ASCII text message examples
		Example - create an ASCII text message in a table - use null
			character to detect end
		Example - create an ASCII text message in a table - use null
			character to detect end - second line of data
		Example - create a text string - use null character to detect end
		Example - create an ASCII character string - use null character
			to detect end
