The CPTS module contains a 32-bit time stamp value (CPSW_CPTS_EVENT_0_REG). The counter upper bits are maintained by host software. The rollover event indicates to software that the time stamp counter has rolled over from 0xFFFF FFFF to 0x0000 0000 and the software-maintained upper count value should be incremented. This event occurs only in 32-bit mode.
