SF32LB58 bus question

Troubleshooting
1

Chip: SF32LB58
Manual: UM5801-SF32LB58x-CN V0.4.3

Questions

  1. The text description and figures regarding ACPU in the manual seem inconsistent? I only see A2HP in the diagram, but not HP2LP.
  2. Are HCPU and ACPU on the same bus matrix, or are they on two separate bus matrices?
  3. It appears the manual does not indicate which bus matrix MPI4 is connected to.

  1. Upon review, there is a misquotation of Figure 1-1 and Figure 1-3 in this version of the 58x user manual. The correct figures can be temporarily referenced from the chip datasheet: https://downloads.sifli.com/user%20manual/DS5801-SF32LB58x-芯片技术规格书%20V1p8p3.pdf
  2. HCPU and ACPU are two independent matrices that can access each other. ACPU accesses LPSYS via A2HP → HP2LP.
  3. MPI4 is described in the correct figure.
