Please take a look in the user manual at https://www.infineon.com/dgdl/Infineon-tc27xD_um_v2.2-UM-v02_02-EN.pdf?fileId=5546d46259d9a4bf015a84..., specifically table 2-16 (CPU access latencies).

Note that the table doesn't have the LMU latency though. Seeing if I can find that....

No, can't find it, but it should be similar to accessing other DSPR/PSPR.
