SC_LAT3 supports the following main features:
- Eight probe inputs:
- Probe 0: DSP1 MDMA
- Probe 1: DSP1 EDMA
- Probe 2: DSP2 MDMA
- Probe 3: DSP2 EDMA
- Probe 4: IVA
- Probe 5: GPU P1
- Probe 6: GPU P2
- Probe 7: BB2D P1
- Four 32-bit counters shared concurrently:
- Counter 0 with one filter
- Counter 1 with one filter
- Counter 2 with one filter
- Counter 3 with one filter
- Filtering according to:
- L3 target
- Access priorities
- 10-bit counter for latency measurement
- 32-bit collecting window counter
- Identifier is 0x4 (tie-off value)
- Dumps frames at slave address 0x19 (L3_INSTR)
