3.3.32. Component identification registers

The pcell_id_[3:0] Register characteristics are:


When concatenated, these four registers return 0xB105F00D

Usage constraints

No usage constraints.


Available in all configurations of the DMC.


See the register summary in Table 3.1.

These registers can be treated conceptually as a single register that holds a 32-bit Component identification value. You can use the register for automatic BIOS configuration.

Figure 3.38 shows the register bit assignments.
