(There is no claim of backward
compatibility for these registers.)
See specific
registers and
bits.
Note:
1. There are new registers and bits. For example:
a. Registers 7 and 8 are new (that is, the ICS 1890 does not have these registers).
b. Registers 20 through 31 are new ICS test registers.
2. For some bits (such as the model number and revision number bits), the default values are changed.
