PROGRAMMING THE PROGRAMMING EXECUTIVE (CONTINUED)
Command
(Binary)
Data
(Hex)
Description
Step 7: Load W0:W5 with the next 4 words of packed programming executive code and initialize W6 for
programming. Programming starts from the base of executive memory (0x800000) using W6 as a read
pointer and W7 as a write pointer.
