3.3.10. PrimeCell Identification Registers 0-3

The SMCPCellID0-3 Registers are read-only. They are four 8-bit registers, that span address locations 0xFF0-0xFFC. The read-only registers can conceptually be treated as a single 32-bit register. The register is used as a standard cross-peripheral identification system.

Figure 3.10 lists the register bit assignments.

PrimeCell Identification Register 0

The SMCPCellID0 Register is a read register. It is hard-coded and the fields in the registers determine the reset value.

Table 3.16 lists the register bit assignments.
