I couldn’t find an equate file of the registers for the 68HC11 anywhere online, so I just typed it all in myself. To spare others from the same tedium I am posting it here in hopes that anyone who needs it can find it easily. The file includes both the extended addresses of each of the HC11 registers, but also the offsets from $1000 for use with indexed addressing. To use it, just put the file in the same folder as your program and insert the following code at the top of your assembly program and you will be able to call all of the registers by name:
#include "EQU.txt"
Hopefully you find it useful.
