The CPTS_COMP output is asserted for CPSW_CPTS_TS_COMP_LEN_REG[31-0] TS_COMP_LENGTH periods when the CPSW_CPTS_EVENT_0_REG[31-0] TIME_STAMP value (lowe 32-bits) compares with the CPSW_CPTS_TS_COMP_VAL_REG[31-0] TS_COMP_VAL and the length value is non-zero. The CPTS_COMP rising edge occurs three CPTS_RFT_CLK clock periods after the values compare. A timestamp compare event is pushed into the event FIFO when CPTS_COMP is asserted. The polarity of the CPTS_COMP output is determined by the CPSW_CPTS_CONTROL_REG[2] TS_COMP_POLARITY bit. The output is asserted low when the polarity bit is 0h.
