Revision History

This data sheet revision history highlights the technical changes made to the SPRS222D device-specific data

sheet to make it an SPRS222E revision.

Scope: Applicable updates to the C64x device family, specifically relating to the TMS320DM641/TMS320DM640

devices, have been incorporated.

8−bit TSI Video Port mode now supported.

Added the device-specific information supporting the TMS320DM641/TMS320DM640 silicon revision 2.0, 1.2 and

1.1 devices, which are now in the production data (PD) stage of development.
