26.5.2.47 Slot Status Counter Registers (SSCR0–SSCR3)
Each of these four registers provides the slot status counter value for the previous communication cycle(s)
and is updated at the cycle start. The provided value depends on the control bits and fields in the related
internal slot status counter condition register SSCCRn, which can be programmed by using the Slot Status
Counter Condition Register (SSCCR). For more details, see Section 26.6.18.4, Slot Status Counter
Registers.
