Hi all, This is my first time using the PIC controllers although I have had a reasonable amount of experience using the HC11. I have a question about indirect addressing data in the program area. I have an external compass unit which has a lot of commands that I want to access with the 16C63. I want to store these commands in the program memory and then indirectly address these commands to be able to transmit them to the compass unit. I have found app notes regarding this for higher level controllers but not the 16C63. Is this possible or do I haveto load the commands into the data area to indirectly address them with this controller. Peter G.
