The CPTS_SYNC output is a selected bit of the [31-0]TIME_STAMP counter value. One of bits 17-31 can be selected in CPSW_CPTS_CONTROL_REG[31-28] TS_SYNC_SEL. The CPTS_SYNC output is disabled when CPSW_CPTS_CONTROL_REG[31-28] TS_SYNC_SEL is zero.
If the selected counter bit is 1 at the time when TS_SYNC_SEL value is written then a rising edge will not occur on the CPTS_SYNC output. A rising edge will occur on the CPTS_SYNC output upon the next transition to 1 of the selected counter bit. The TS_SYNC_SEL value must be written to zero before changing to a different non-zero value. No events are generated due to the CPTS_SYNC operation. The CPTS_SYNC output is two CPTS_RFT_CLK periods after the actual count value.
