APB ComponentsThe four, 8-bit PrimeCell identification registers are described in the followingsubsections:• PrimeCell Identification Register 0• PrimeCell Identification Register 1• PrimeCell Identification Register 2• PrimeCell Identification Register 3 on page 4-23.PrimeCell Identification Register 0The WDOGPCELLID0 Register is hard-coded and the fields within the registerdetermine the reset value. Table 4-24 lists the register bit assignments.Table 4-24 WDOGPCELLID0 Register bit assignmentsBits Name Description[31:8] - Reserved, read undefined, must read as zeros[7:0] WdogPCellID0 These bits read back as 0x0DPrimeCell Identification Register 1The WDOGPCELLID1 Register is hard-coded and the fields within the registerdetermine the reset value.
