10. Protection
The protection function protects important registers from being easily overwritten if a program runs out of control.
The registers protected by the PRCR register are as follows:
• Registers protected by PRC0 bit: Registers CM0, CM1, CM3, and OCD
• Registers protected by PRC1 bit: Registers PM0 and PM1
• Registers protected by PRC3 bit: Registers OCVREFCR, VCA2, and VW2C
