showed four registers that can be protected 8-bit wise. In
registers with 32-bit protection are shown:
Figure 4-6. Change lock settings for 16-bit protected addresses
it is shown that the data written to SLBR
n
.SLB[0] is automatically written
to SLBR
n
.SLB[1] also. This is done as the address reflected by SLBR
n
.SLB[0] is protected 16-bit wise.
Note that in this case the write enable SLBR
n
.WE[0] must be set while SLBR
n
.WE[1] does not matter. As
the enable bits SLBR
n
.WE[3:2] are cleared the lock bits SLBR
n
.SLB[3:2] remain unchanged.
In the example on the left side of
the data written to SLBR
n
.SLB[0] is mirrored to
SLBR
n
.SLB[1] and the data written to SLBR
n
.SLB[2] is mirrored to SLBR
n
.SLB[3], as for both registers
the write enables are set.
a 32-bit wise protected register is shown. When SLBR
n
.WE[0] is set the data written to
SLBR
n
.SLB[0] is automatically written to SLBR
n
.SLB[3:1] also. Otherwise SLBR
n
.SLB[3:0] remains
unchanged.
