PrimeCell Identification Registers
The IPCMPCellID0-3 Registers are four 8-bit registers, that span address locations
0xFF0-0xFFC
. You can conceptually treat the registers as a single 32-bit register. The
register is used as a standard cross-peripheral identification system.
Figure 3-9 shows the register bit assignments.
Figure 3-9 PrimeCell Identification Register bit assignments
The four PrimeCell Identification Registers are described in the following subsections:
•
PrimeCell Identification Register 0
•
PrimeCell Identification Register 1
on page 3-23
•
PrimeCell Identification Register 2
on page 3-23
•
PrimeCell Identification Register 3
on page 3-23.
PrimeCell Identification Register 0
The hard-coded IPCMPCellID0 Register defines the reset value. Table 3-19 lists the bit
assignments for the IPCMPCellID0 Register.
