23.5 Protection
Set the PRC2 bit in the PRCR register to 1 (write enabled) and then write to given address, and the PRC2
bit will be set to 0 (write protected). The registers protected by the PRC2 bit should be changed in the next
instruction after setting the PRC2 bit to 1. Make sure no interrupts or no DMA transfers will occur between the
instruction in which the PRC2 bit is set to 1 and the next instruction.
