 * Description:  There are seven instances of translation table entry   *
 * registers. Each register maps a Shub Big Window to a 48-bit          *
 * address on Crosstalk.                                                *
 * For M-mode (128 nodes, 8 GBytes/node), SysAD[31:29] (Big Window      *
 * number) are used to select one of these 7 registers. The Widget      *
 * number field is then derived from the W_NUM field for synthesizing   *
 * a Crosstalk packet. The 5 bits of OFFSET are concatenated with       *
 * SysAD[28:0] to form Crosstalk[33:0]. The upper Crosstalk[47:34]      *
 * are padded with zeros. Although the maximum Crosstalk space          *
 * addressable by the Shub is thus the lower 16 GBytes per widget       *
 * (M-mode), however only <SUP >7</SUP>/<SUB >32nds</SUB> of this       *
 * space can be accessed.                                               *
 * For the N-mode (256 nodes, 4 GBytes/node), SysAD[30:28] (Big         *
 * Window number) are used to select one of these 7 registers. The      *
 * Widget number field is then derived from the W_NUM field for         *
 * synthesizing a Crosstalk packet. The 5 bits of OFFSET are            *
 * concatenated with SysAD[27:0] to form Crosstalk[33:0]. The IOSP      *
 * field is used as Crosstalk[47], and remainder of the Crosstalk       *
 * address bits (Crosstalk[46:34]) are always zero. While the maximum   *
