TMS320F28388D: .const section is not aligned as specified in link command file

Tool/software:

Hello, Experts

I've set the section, .const, aligned on a 16-byte boundary as below.

.const           : > CMBANK0_SECTOR9_13, ALIGN(16)

But I found that the section didn't be made with align(16) in the map file below.

Contrary to what I expected, The length of the section is 0x1C23, and it is not aligned to16-byte alignment.

Actually I want to align the .const section on a 16-byte boundary, such as 0x1C30, instead of 0x1C23.

.const     0    00275d00    00001c23 

Why does this happen? How can I make the section algiend on a 16-byte boundary?

Thansks,

Best Regards.
