3.3.14 SMC PrimeCell Identification Registers <0-3> at 0x1FF0-0x1FFC
The smc_pcell_id Registers are four 8-bit wide registers, that span address locations
0xFF0-0FFC
. The registers can conceptually be treated as a single register that holds a
32-bit PrimeCell ID value. You can use the register for automatic BIOS configuration.
The smc_pcell_id Register is set to
0xB105F00D
. The register can be accessed with one
wait state. Table 3-19 lists the register bit assignments.
Figure 3-19 shows the register bit assignments.
