Bits 31 to 0: Frames Aborted Due to FIFO Under Run Counter (TXFRMU31 to TXFRMU0). 32-bit value indicating the number of frames aborted due to FIFO under run. Each time a frame is aborted due to FIFO under run, this counter is incremented by 1. This counter resets only upon device reset, does not saturate, and rolls over to zero upon reaching the maximum value. The user should ensure that the measurement period is less than the minimum length of time required for the counter to increment 2^32-1 times at the maximum frame rate. The user should store the value from the beginning of the measurement period for later calculations, and take into account the possibility of a rollover occurring.
