Bit 7: Performance Monitoring Update Mode (PMUM) – When 0, a performance monitoring update is initiated by
the LPMU register bit. When 1, a performance monitoring update is initiated by the global or port PMU register bit.
Note: If the LPMU bit or the global or port PMU bit is one, changing the state of this bit may cause a performance
monitoring update to occur.
Bit 6: Local Performance Monitoring Update (LPMU) – This bit causes a performance monitoring update to be
initiated if local performance monitoring update is enabled (PMUM = 0). A 0 to 1 transition causes the performance
monitoring registers to be updated with the latest data, and the counters reset (0 or 1). For a second performance
monitoring update to be initiated, this bit must be set to 0, and back to 1. If LPMU goes low before the PMS bit
goes high; an update might not be performed. This bit has no affect when PMUM=1.
Bit 5: Receive New Pattern Load (RNPL) – A zero to one transition of this bit will cause the programmed test
pattern (QRSS, PTS, PLF[4:0}, PTF[4:0], and BSP[31:0]) to be loaded in to the receive pattern generator. This bit
