28.16.21 PMC Write Protect Mode Register
Name:
Address:
Access:
Reset:
• WPEN: Write Protect Enable
0 = Disables the Write Protect if WPKEY corresponds to 0x504D43 (“PMC” in ASCII).
1 = Enables the Write Protect if WPKEY corresponds to 0x504D43 (“PMC” in ASCII).
Protects the registers:
• WPKEY: Write Protect KEY
Should be written at value 0x504D43 (“PMC” in ASCII). Writing any other value in this field aborts the write operation of the
