This mode is functional regardless of the ratio between the configuration interface frequency and the functional clock frequency. Recommended functional frequency range is freq(timer) >= freq(interface clock)/4.
Read non-posted mode is used if TIMER_TSICR[2] POSTED = 0x0 and TIMER_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 configuration 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 TIMER_TCRR, TIMER_TCAR1, TIMER_TCAR2, TIMER_TCVR, and TIMER_TOWR, which need resynchronization from functional to interface clock domains.
