11 The CoreSight Embedded Cross Trigger (ECT) consists of CTI devices connected
18 The CTI component properties define the connections between the individual
19 CTI and the components it is directly connected to, consisting of input and
21 output hardware trigger signals (8 each for v1 CTI, 32 each for v2 CTI). The
31 In general the connections between CTI and components via the trigger signals
32 are implementation defined, except when the CTI is connected to an ARM v8
36 between CTI and the CPU core and ETM if present. In the case of a v8
37 architecturally connected CTI an additional compatible string is used to
