NOTES :
1. Set the PRC1 bit in the PRCR register to “1” (w rite enable) before rew riting to this register.
2. The PM12 bit is set to “1” by a program (It remains unchanged even if it is set to “0”).
When the CSPRO bit in the CSPR register is set to “1” (selects count source protect mode), the PM12 bit is
automatically set to “1”.
