Can I write Serial Quick Turn Programming (SQTP℠) data without overwriting code program memory using IPE?

It is possible to bypass code regions when programming a device with MPLAB® IPE. This is because MPLAB IPE provides the ability to select the memory regions that are programmed, while simultaneously preserving the contents of another region. The ability of MPLAB IPE to protect memory depends upon the size of the application code.

The smallest area that MPLAB IPE can preserve is 0x3F (e.g. 0x7FC0 - 0x7FFF). The start address value must be equal to 0x40*n. The end value must be equal to 0x40*n-1.
