While the Processing System (PS) and Processor Configuration Access Port (PCAP) are in control of the configuration logic, the Programmable Logic (PL) and Internal Configuration Access Port (ICAP) are locked out of the configuration logic.
Similarly while the ICAP is in control, the PCAP and PS will be locked out. How do I switch between them?
All PCAP or ICAP operations must be completed before switching to the other.
A typical use case where you might need to switch between PCAP and ICAP is when using SEMIP or Post_CRC.
To switch from PCAP to ICAP:
Clear PCAP_PR (bit 27) in the PS device configuration control register (DEVCFG CTRL, address 0xF8007000).
To switch ICAP back to PCAP:
If using POST_CRC:
If using SEM IP:
