The time stamp value is a 32-bit value that increments on each RCLK rising edge when CPTS_EN is set to 1. When CPTS_EN is cleared to 0, the time stamp value is reset to 0.
If more than 32-bits of time stamp are required by the application, the host software must maintain the necessary number of upper bits. The upper time stamp value should be incremented by the host when the rollover event is detected.
For test purposes, the time stamp can be written via the time stamp load function (CPTS_TS_LOAD_VAL_REG and CPTS_TS_LOAD_EN_REG).
The TS_INC_VAL[2:0] value must be zero in 32-bit mode. Nudge and PPM adjustments are not supported in 32-bit mode.
