Note Set bit 27 to bit 24 to 0.
Cautions 1. ROM address match functions are valid only for internal ROM.
2. This cannot be used in single-chip mode 1.
3. The lower 2 bits (EVAU1, EVAU0) are masked.

12.4.3 Chip ID registers (TID0 to TID2)

The chip ID registers are stored in NBD space 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.
