This mode is functional whatever the ratio between the OCP interface frequency and the functional clock frequency are. The recommended functional frequency range is freq(timer) < freq(OCP) / 4.
Read posted mode is used if TSICR[2] POSTED = 0x1 or TSICR[3] READ_MODE is set to 0. This mode uses a posted-read scheme for reading any internal timer register. The read transaction is immediately acknowledged on the OCP interface, and the value to be read has been resynchronized. With this method, neither the interconnect nor the device that requested the read transaction are stalled.
Read posted mode applies to TCRR, TCAR1, TCAR2, TCVR, and TOWR, which need resynchronization from functional to OCP clock domains.
