C6745 device speed range identification

Other Parts Discussed in Thread: TMS320C6745

Hello,

The C6745 DSP comes in two speed ranges, a 375 MHz version and a 456 MHz version.  Can I read a register to determine the speed range?  The TMS320C6745 data sheet describes a JTAG ID register (DEVIDR0 @ 0x01C14018) that contains the product variant, part number, manufacturer, and lsb, but does not mention the possible values beyond the silicon revision.  Does this register provide the information I'm interested in, or is there another register?  (I do not have the 456 MHz version to verify yet.)

Thanks!
