Option Registers (OR n )—GPCM Mode
GPCM address mask. Masks corresponding BR n bits. Masking address bits independently allows external
devices of different size address ranges to be used. Address mask bits can be set or cleared in any order in
the field, allowing a resource to reside in more than one area of the address map.
0 Corresponding address bits are masked and therefore don’t care for address checking.
1 Corresponding address bits are used in the comparison between base and transaction addresses.
