13.5.2.47 Slot Status Registers (SSR0–SSR7)
Each of these eight registers holds the status vector of the slot specied in the corresponding internal slot
register is updated after the end of the corresponding slot as shown in
Figure 13-142. The register bits are
Module Base + 0x0068 (SSR0)
Module Base + 0x006A (SSR1)
Module Base + 0x006C (SSR2)
Module Base + 0x006E (SSR3)
Module Base + 0x0070 (SSR4)
Module Base + 0x0072 (SSR5)
Module Base + 0x0074 (SSR6)
Module Base + 0x0076 (SSR7)
