This mode is used if the TSICR[2] POSTED bit is set to 0 (default value). It uses a nonposted write scheme to update any internal register. Therefore, the write transaction is not acknowledged on the L4 interface until the effective write operation occurs after the resynchronization in the timer functional clock domain. The drawback is that the interconnect and the device that requested the write transaction are stalled during this period.
The same full resynchronization scheme is used for a read transaction, and the same stall period applies. A register read following a write to the same register is always coherent.
This mode is functional regardless of the ratio between the OCP interface frequency and the timer clock frequency.
