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 8.8 shows the protect register. The values in the processor

tant outputs can be allocated to port P9.
If, after “1” (write-enabled) has been written to the PRC2 (bit 2 at address 000A
address, the bit automatically reverts to “0” (write-inhibited). Change port P9 input/output and function
select register A3 immediately after setting "1" to PRC2. Interrupt and DMA transfer should not be inserted
between instructions. However, the PRC0 (bit 0 at address 000A
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”.
