upon reset. Flash programming commands use the top 32 bytes of on-chip RAM. The stack is located at RAM top - 32. The
maximum stack usage is 256 bytes and it grows downwards.
RAM used by IAP command handler
Flash programming commands use top 32 bytes of on-chip RAM. The maximum stack usage in the user allocated stack space
