The content of this register depends on the value of the T2_CFG bit in the Timer Configuration and Control
Register (TICCR) . For a detailed description of timer T2, refer to Section 26.6.17.2, Absolute / Relative
Timer T2.
NOTE
If timer T2 is configured as an absolute timer and the application modifies
the values in this register while the timer is running, the change becomes
effective immediately and the timer T2 will expire according to the changed
values.
If timer T2 is configured as a relative timer and the application changes the
values in this register while the timer is running, the change becomes
effective when the timer has expired according to the old values.
26.5.2.44 Slot Status Selection Register (SSSR)
This register is used to access the four internal non memory-mapped slot status selection registers SSSR0
to SSSR3. Each internal registers selects a slot, or symbol window/NIT, whose status vector will be saved
in the corresponding
Slot Status Registers (SSR0–SSR7) according to Table 26-52 . For a detailed
description of slot status monitoring, refer to Section 26.6.18, Slot Status Monitoring.
