The 64-bit TIME_STAMP can be adjusted by parts per million (PPM) or by parts per hour (PPH). Writing a non-zero value to the TS_PPM[41:0] value enables PPM operations. The adjustment is up or down depending on the TS_PPM_DIR bit. The TIME_STAMP value is increased by the PPM value when TS_PPM_DIR is cleared and decreased by the PPM value when TS_PPM_DIR is set.
