The 64-bit TIME_STAMP value can be adjusted by writing the CPSW_CPTS_TS_NUDGE_VAL_REG[7-0] TS_NUDGE_VAL bit field value which is a two's complement value. A value of FFh will subtract 1 clock cycle from the next incremented 64-bit time stamp value (CPSW_CPTS_EVENT_0_REG[31-0] TIME_STAMP and CPSW_CPTS_EVENT_3_REG[31-0] TIME_STAMP value). A nudge value of 1h will add 1 clock cycle to the next incremented TIME_STAMP[63-0] value. For example, if the current TIME_STAMP value is F06h, and CPSW_CPTS_TS_ADD_VAL_REG[2-0] ADD_VAL = 3h, the next incremented timestamp value would be F0Ah without a nudge and F0Ah +/- [7-0] TS_NUDGE_VAL with a nudge. The [7-0] TS_NUDGE_VAL value is cleared to zero when the nudge has occurred.
