2.0 Electrical Interfaces
2.4 JTAG Interface
2.4.3 Optional Device ID Register
2.4.4 Verification with the Tap Controller
The Bt829B has the optional device identification register defined by the JTAG
specification. This register contains information concerning the revision, actual
part number, and manufacturer’s identification code that is specific to Rockwell.
The TAP controller can access the register via an optional JTAG instruction, as
shown in Table 2-6.
Table 2-6. Device Identification Register
The TAP controller enables you to perform a variety of verification procedures.
Using a set of four instructions, the Bt829B can verify board connectivity at all
digital interfaces and pins. The instructions can be accessed using a state machine
that is standard to all JTAG controllers. They are Sample/Preload, Extest, ID
Code, and Bypass (see Figure 2-16). Refer to the IEEE P1149.1 specification for
details concerning the instruction register and JTAG state machine.
