Bit Protection Scheme Control Bits
00
Scheme disabled - direct access to the
protected bits is allowed.
11
Scheme enabled - the bit field PASS has to be
written with the passwords to open and close
the access to protected bits. (default)
Others:Scheme Enabled.
These two bits cannot be written directly. To change
the value between 11B and 00B, the bit field PASS
must be written with 11000B; only then, will the
MODE[1:0] be registered.
PROTECT_S
2rh
Bit Protection Signal Status Bit
This bit shows the status of the protection.
0
Software is able to write to all protected bits.
1
Software is unable to write to any protected
bits.
PASS
[7:3]
wh
Password Bits
The Bit Protection Scheme only recognizes three
patterns.
11000B Enables writing of the bit field MODE.
10011B Opens access to writing of all protected bits.
10101B Closes access to writing of all protected bits
