Where can I find the numbers of cycles for PRU assembly instructions?

The link to PRU Assembly Instructions doesn't have the cycle count.
processors.wiki.ti.com/.../PRU_Assembly_Instructions

I only found the READ latencies but not for each assembly instructions.

Hi,

All available information about PRU is located in the following link:
processors.wiki.ti.com/.../PRU-ICSS

For functional description, you can check the device TRM (www.ti.com/.../spruhy8e.pdf), Section 6.4 Programmable Real-Time Unit Subsystem and Industrial Communication Subsystem (PRU-ICSS).

Best Regards,
Yordan

The link and TRM don't have the cycle counts of assembly instructions.
