ID Code Register c0
This is a read-only register that returns the 32-bit device ID code.
You can access the ID Code Register by reading CP15 register c0 with the Opcode_2
field set to any value other than 1 or 2. For example:
The contents of the ID Code Register are shown in Table 2-5.
Cache Type Register c0
This is a read-only register that contains information about the size and architecture of
the Instruction Cache (ICache) and Data Cache (DCache) enabling operating systems
to establish how to perform such operations as cache cleaning and lockdown.
You can access the cache type register by reading CP15 register c0 with the Opcode_2
field set to 1. For example:
The format of the Cache Type Register is shown in Figure 2-2 on page 2-9.
