Protection
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. Figure 1.11.1 shows the protect register. The values in the processor
mode register 0 (address 000416), processor mode register 1 (address 000516), system clock control reg-
ister 0 (address 000616), system clock control register 1 (address 000716) and port P0 direction register
(address 00E216) can only be changed when the respective bit in the protect register is set to “1”. There-
fore, important outputs can be allocated to port P0.
If, after "1" (write-enabled) has been written to bit "enables writing to port P0 direction register" (bit 2 at
address 000A16), a value is written to any address, the bit automatically reverts to "0" (write-inhibited).
The system clock control registers 0 and 1 and oscillation stop detection register write-enable bit (bit 0 at
000A16) and processor mode register 0 and 1 write-enable bit (bit 1 at 000A16) do not automatically return
to “0” after a value has been written to an address. The program must therefore be written to return these
bits to “0”.

Nothing is assigned.
In an attempt to write to these bits, write “0”. The value, if read, turns out to be
indeterminate.
Note: Writing a value to an address after “1” is written to this bit returns the bit
to “0” . Other bits do not automatically return to “0” and they must therefore
be reset by the program.
