AM2434: If any possible, reduce FSI registers read/write latency

AM2434: Do registers read latency improve in MCU+ SDK 09.01.00

Part Number: AM2434

Hi Experts,

    About the CPU register read latency improved, the related e2e article described that issue will be fixed in MCU+ SDK 09.01.00.

    AM2434: If any possible, reduce FSI registers read/write latency - Arm-based microcontrollers forum - Arm-based microcontrollers - TI E2E support forums

    Then, MCU+ SDK 09.01.00 was released. But the release notes didn't describe the related information for read latency improved.

    So, I want to know the CPU register read latency improved in MCU+ SDK 09.01.00 or not. Is the related JIRA ticket solved and merge to MCU+ SDK 09.01.00 ?

    And if the latency has improved,

           How much latency time will be reduced in MCU+SDK ver.09.01.00 ?

           Will this latency improvement have the same effect on both R5f and PRU?

Best Regards

Bolt
