The CCRs are loaded with the contents of the chip configuration bytes (CCBs) after a device reset,
unless the device is entering programming modes (see “Entering Programming Modes” on page
16-13), in which case the programming chip configuration bytes (PCCBs) are used. The CCBs reside in
internal nonvolatile memory at addresses 2018H (CCB0) and 201AH (CCB1).
