Software enable

The software enable is performed when the operating system loads the enable value
into the translation control register (TC). If the enable bit of the TC register is
"e=1", the MMU will be enabled. If the enable bit in the TC register is "e=0", the
MMU will be disabled.

Restrictions when using the emulator with the
MMU turned on

There are only three restrictions: you must use a foreground monitor, it must not be
write-protected, and you must map it to address space that the MMU translates 1:1
(logical=physical) for supervisor accesses.

You must use a foreground monitor. The background monitor does not have the
capabilities to support the MMU functions. The foreground monitor can operate
with the MMU turned on.

You must map the monitor code to address space that the MMU translates 1:1 for
supervisor accesses.  The emulator executes monitor code to implement many of its
emulation features.  The emulator must be able to find the monitor code whether
the MMU is turned on or off.  By mapping the monitor into address space that has a
1:1 translation, the monitor stays within known address space at all times, and the
emulator can always find it when it needs to use it.  This mapping is described at
the end of Chapter 8, "Configuring the Emulator."

Be sure that no write-protection exists in the MMU mapping for the monitor.

Caution

Make sure your translation tables are valid.  Turning on the MMU can cause your
program or emulator to fail if the MMU tables are not set up correctly.  The address
space where the program is executing can change when the MMU is turned on or
turned off.  Stack space or other data spaces can move.  Breakpoints that have been
set can be lost.
