Table 36 describes how the PWT signal is driven based on the
values of the PWT bits and the PG bit of CR0.
Table 36. PWT Signal Generation
Notes:
1. PWT is taken from PTE or PDE.
Table 37 describes how the PCD signal is driven based on the
values of the CD bit of CR0, the PCD bits, and the PG bit of
CR0.
Table 37. PCD Signal Generation
Notes:
1. PCD is taken from PTE or PDE.
Table 38 describes how the CACHE# signal is driven based on
the cycle type, the CI bit of TR12, the PCD signal, and the
UWCCR model-specific register.
