This register is used to access and program the four internal non-memory mapped Slot Status Counter
Condition Registers SSCCR0 to SSCCR3. Each of these four internal slot status counter condition
registers defines the mode and the conditions for incrementing the counter in the corresponding
Counter Registers

Write Mode — This control bit defines the write mode of this register.
0 Write to all fields in this register on write access.
1 Write to SEL field only on write access.
Selector — This field selects one of the four internal slot status selection registers for access.
00 select SSSR0.
01 select SSSR1.
10 select SSSR2.
11 select SSSR3.
Slot Number — This field specifies the number of the slot whose status will be saved in the corresponding
slot status registers.
Note: If this value is set to 0, the related slot status register provides the status of the symbol window after the
(SSCR0–SSCR3). The correspondence is given in
NIT start, and provides the status of the NIT after the cycle start.
