Protection
The protection function is provided so that the values in important registers cannot be changed in the event
that the program runs out of control. Fig.WA-6 shows the protect register. The values in the processor mode
register 0 (address 000416), processor mode register 1 (address 000516), system clock control register 0
(address 000616), system clock control register 1 (address 000716) can only be changed when the respec-
tive bit in the protect register is set to “1”.

Nothing is assigned.
In an attempt to write to these bits, write “0”. The value, if read, turns out to be
indeterminate.
