Filename: _hal_oad.c
Revised: $Date: 2010-07-08 18:39:25 -0700 (Thu, 08 Jul 2010) $
Revision: $Revision: 22957 $
Description: This module contains optionally-compiled Boot Code to support OAD.
The rest of the functionality is the H/W specific drivers to read/write
the flash/NV containing the ACTIVE and the DOWNLOADED images.
Notes: This version targets the Texas Instruments CC253x family of processors.
