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 11
B and 00B, the bit field PASS
must be written with 11000
B; 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.
11000
B Enables writing of the bit field MODE.
10011
B Opens access to writing of all protected bits.
10101
B Closes access to writing of all protected bits
