The funnels combine packetized traces from several debug components onto the ATB bus. Each funnel includes memory-mapped registers for programming enable/disable, priority, etc. (refer to the FUNNEL3P and FUNNEL4P register sets).

There are three funnels:

Funnel 0 connects to RPU in LPD (routed to FPD, FUNNEL3P).

Funnel 1 connects to the APU MPCore (FPD, FUNNEL4P).

Funnel 2 connects to Funnel 0, funnel 1, and STM (FPD, FUNNEL4P).
