Set the PRC1 bit in the PRCR register to 1 (w rite enable) before rew riting the PM1 register.
The PM12 bit is set to 1 by a program (and remains unchanged even if 0 is w ritten to it).
When the CSPRO bit in the CSPR register is set to 1 (count source protect mode enabled), the PM12 bit is
automatically set to 1.
