16.4.1.3 Chip Select Control Registers (CSCR0–CSCR7)
Each CSCR, shown in
activation of each chip select. Note that to support the external boot chip select, CS0, the CSCR0
reset values differ from the other CSCRs. CS0 allows address decoding for boot ROM before
system initialization.

Base address mask. Defines the chip select block by masking address bits. Setting a BAM
bit causes the corresponding CSAR bit to be ignored in the decode.
0 Corresponding address bit is used in chip select decode.
1 Corresponding address bit is a don’t care in chip select decode.
The block size for CS[7:0] is 2

Write protect. Controls write accesses to the address range in the corresponding CSAR.
Attempting to write to the range of addresses for which CSARn[WP] = 1 results in the
appropriate chip select not being selected and an access error exception will occur.
0 Both read and write accesses are allowed.
1 Only read accesses are allowed.
Reserved, should be cleared.
Valid bit. Indicates whether the corresponding CSAR, CSMR, and CSCR contents are
valid. Programmed chip selects do not assert until V is set (except for CS0, which acts as
the global chip select). Reset clears each CSMRn[V].
