Programming the Programming
Executive to Memory
5.4.1
OVERVIEW
If it is determined that the programming executive is
not present in executive memory (as described
Programming Executive”), it must be programmed
into executive memory using ICSP, as described in
Storing the programming executive to executive
memory is similar to normal programming of code
memory. Namely, the executive memory must be
erased, and then the programming executive must be
programmed 64 words at a time. Erasing the last page
of executive memory will cause the FRC oscillator
calibration settings and device diagnostic data in the
Diagnostic and Calibration Words, at addresses
8007F0h to 8007FEh, to be erased. In order to retain
this calibration, these memory locations should be read
and stored prior to erasing executive memory. They
should then be reprogrammed in the last words of pro-
gram memory. This control flow is summarized in
