How to get ISO 100 on 645D

I am trying to use ISO 100 but when I select the ISO button I can only get 200. How can I get 100? Thanks

Do you have highlight correction on? I don't own a 645D, but that is the the setting that usually puts your base iso up to 200.

Straight out of page 46 of the owner's manual:

"You can expand the sensitivity setting to ISO 100 to 1600 with [3. Expand Sensitivity.] in the [C1] menu.

Enable expanded ISO in the menu as described above, and make sure highlight correction is disabled.
