4.4.1 Overview

If it is determined that the Programming Executive is not present in the executive memory (as described in Confirming the Presence of the Programming Executive), the Programming Executive must be programmed into the executive memory.

Figure 4-5 shows the high-level process of programming the Programming Executive into executive memory. First, the ICSP mode must be entered, and the executive memory must be erased. Then, the Programming Executive is programmed and verified. Finally, ICSP mode is exited.
