CODECOMPOSER: About the usable capacity of CC27xx HSM

Hello,

We are considering using CC2745 for our project.
Please tell me about the manual for CC27xx Datasheet.

For example, CC2745P10-Q1 has 1MB of Flash.
Does this 1MB of Flash include not only non-secure program code and non-volatile data, but also secure (HSM) program code and non-volatile data?
And, in the case of PG2.0, the maximum size of the area that can be used as HSM is 128KB, so is it correct to store secure program code and non-volatile data in 128KB?

Thanks,

Manabe
