12.4.3 Chip ID registers (TID0 to TID2)
The chip ID registers are stored in NBD spaces 000H to 002H. By reading the ID codes in the chip ID registers
from the NBD tool in NBD mode, the semiconductor manufacturer, CPU code, and specific product type can be
identified. The chip ID registers have fixed values for each product.
The chip ID registers (TID0 to TID2) are read-only registers.
