Effects of the Control Register on TCM interface
The M bit of the Control Register, when combined with the En bit in the respective TCM
region register c9, directly affects the TCM interface behavior, as shown in Table 2-13.

Behavior
All instruction fetches are from the external memory (AHB).
All instruction fetches are from the TCM interface, or from external memory
(AHB), depending on the setting of the base address in the instruction TCM
region register. No protection checks are made. All addresses are flat mapped.
That is, VA = MVA= PA.

All instruction fetches are from the TCM interface, or from the ICache/AHB
interface, depending on the setting of the base address in the Instruction TCM
region register. Protection checks are made. All addresses are remapped from
VA to PA, depending on the page entry. That is, the VA is translated to an MVA,
and the MVA is remapped to a PA.
All data accesses are to external memory (AHB).
All data accesses are to the TCM interface, or to the external memory, depending
on the setting of the base address in the data TCM region register. No protection
checks are made. All addresses are flat mapped. That is, VA = MVA= PA.
