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 937
“ADC Channel Sequence 1 Register” on page 939
“ADC Channel Sequence 2 Register” on page 940
“ADC Channel Enable Register” on page 941
“ADC Channel Disable Register” on page 942
“ADC Extended Mode Register” on page 951
“ADC Compare Window Register” on page 952
“ADC Analog Control Register” on page 954
“ADC Touchscreen Mode Register” on page 955
“ADC Trigger Register” on page 960
• 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.
