Access:
• WPEN: Write Protect Enable
0 = Disables the Write Protect if WPKEY corresponds to 0x414443 (“ADC” in ASCII).
1 = Enables the Write Protect if WPKEY corresponds to 0x414443 (“ADC” in ASCII).
Protects the registers:
“ADC Mode Register” on page 661
“ADC Channel Sequence 1 Register” on page 663
“ADC Channel Sequence 2 Register” on page 664
“ADC Channel Enable Register” on page 665
“ADC Channel Disable Register” on page 666
“ADC Extended Mode Register” on page 674
“ADC Compare Window Register” on page 675
• WPKEY: Write Protect KEY
Should be written at value 0x414443 (“ADC” in ASCII). Writing any other value in this field aborts the write operation of the
WPEN bit. Always reads as 0.
