CCS/TMS320F28377D: Strange memory issue in TMS320F28377D

Part Number:TMS320F28377D

Tool/software: Code Composer Studio

Hello.

I build the project in CCS 7.1.0 and generate a HEX-file using standart C2000 utility.

Here are first two lines of HEX-file:

%1263980008000048E6
%4E68C800082000C6080C0814081C083A0858087808A808B408D308E708F708070817083B084C08

Then I go to debug mode, load the same project to flash and look at Memory browser. I expect to see the same bytes which I see in HEX, but what I see is (16-bit HEX TI style):

0x00080000    0048    B1E6    FFFF    FFFF    FFFF    FFFF    FFFF    FFFF
...
0x00082000     77C6    0008    780C    0008    7814    0008    781C    0008
0x00082008     783A     0008     7858     0008     7878     0008     78A8     0008
0x00082010     78B4     0008     78D3     0008     78E7     0008     78F7     0008
0x00082018     7907     0008     7917     0008     793B     0008     794C     0008

It looks like the data bytes from the HEX-file (48 E6 C6 08 0C 08...) are interleaved with 00 B1 77 00 78 00...

What is the origin of these unexpected bytes? How to consider them when doing Flash API programming/verifying?
