3.3.2.44 Slot Status Registers (SSR0–SSR7)
Each of these eight registers holds the status vector of the slot specified in the corresponding internal slot
status selection register, which can be programmed using the Slot Status Selection Register (SSSR). Each
register is updated after the end of the corresponding slot as shown in Figure 3-138. The register bits are
directly related to the protocol variables and described in more detail in Section 3.4.18, “Slot Status
Monitoring”.
