The CT_R4F_ID register provides information that identifies the revision status of the CT-R4F Core Tile.
This information will be useful if you need to contact ARM Support for assistance.
The CT_R4F_ID register is at serial stream address 0x1000
.
Figure 4.11 shows the bit
allocations within the CT_R4F_ID register.
Table 4.22 shows the bit assignments within the register.
