0 | TS_PUSH | Time stamp event push - When a logic high is written to this bit a time stamp event is pushed onto the event FIFO. The time stamp value is the time of the write of this register, not the time of the event read. The time stamp value can then be read on interrupt via the event registers. Software should not push a second time stamp event onto the event FIFO until the first time stamp value has been read from the event FIFO (there should be only one time stamp event in the event FIFO at any given time). This bit is write only and always reads zero. | W | 0x0 |

31:0 | TS_LOAD_VAL | Time Stamp Load Value - Writing the CPTS_TS_LOAD_EN[0] TS_LOAD_EN bit causes the value contained in this register to be written into the time stamp. The time stamp value is read by initiating a time stamp push event, not by reading this register. When reading this register, the value read is not the time stamp, but is the value that was last written to this register. | RW | 0x0 |

0 | EVENT_POP | Event Pop - When a logic high is written to this bit an event is popped off the event FIFO. The event FIFO pop occurs as part of the interrupt process after the event has been read in the CPTS_EVENT_LOW and CPTS_EVENT_HIGH registers. Popping an event discards the event and causes the next event, if any, to be moved to the top of the FIFO ready to be read by software on interrupt. | W | 0x0 |
