The PRC2 bit setting in the PRCR register is changed to "0" (write disable) when an instruction is written to
any address after the PRC2 bit is set to "1" (write enable). Write instruction immediately after setting the
PRC2 bit to "1" to change registers protected by the PRC2 bit. Do not generate an interrupt or a DMA
transfer between the instruction to set the PRC2 bit to "1" and the following instruction.
