20. Precautions
20.3 Protection
Set the PRC2 bit to â1â (write enabled) and then write to any address, and the PRC2 bit will be cleared to â0â
(write protected). The registers protected by the PRC2 bit should be changed in the next instruction after
setting the PRC2 bit to â1â. Make sure no interrupts or DMA transfers will occur between the instruction in
which the PRC2 bit is set to â1â and the next instruction.
