Device Identification Code Register
www.ti.com ......................................................................................................................................................... SPNS108B – AUGUST 2005 – REVISED MAY 2008
The device identification code register identifies the silicon version, the technology family (TF), a ROM or flash
device, and an assigned device-specific part number (see Figure 3). The B768 device identification code register
value is 0xn87F.
