This mode is functional regardless of the ratio between the OCP interface frequency and the functional clock frequency. Recommended functional frequency range is freq(timer) >= freq(OCP) / 4.
Read non-posted mode is used if TSICR[2] POSTED = 0x0 and TSICR[3] READ_MODE = 0x1. This mode uses a non-posted read scheme for reading internal timer registers. The read transaction is not acknowledged on the OCP interface until the effective read operation occurs, after the resynchronization in the timer clock domain. The result is that both the interconnect and the device that requested the read transaction are stalled during this period.
This mode applies to TCRR, TCAR1, TCAR2, TCVR, and TOWR, which need resynchronization from functional to OCP clock domains.
