Bit 31 – TS_OVF Timestamp Overflow

ValueDescription
0 RTT_ST.RTTINC2 was set but no new event occurred since the last read of RTT_SR.
1 RTT_ST.RTTINC2 was set and a second event occurred. To avoid any overflow, clear RTTINC2 by reading RTT_SR.

Bits 30:0 – TSTAMP[30:0] Real-Time Timer Value Timestamp

Each time an event triggers the flag RTT_SR.RTTINC2, RTT_VR.CRTV is copied into RTT_TSR.TSTAMP. The field TSTAMP remains stable until the next RTTINC2 event and can be used for event timestamping.
