The IBA[X:0] bits define the content of the target activate IB detection code. The ‘X’ is determined by the IBAL[1:0] bits (b3~2,
IBL,...). The IBA0 bit is the last bit to be detected.
The IBD[X:0] bits define the content of the target deactivate IB detection code. The ‘X’ is determined by the IBDL[1:0] bits (b1~0,
IBL,...). The IBD0 bit is the last bit to be detected.
