Bits 0 - 31: Frames Aborted Due to FIFO Under Run Counter (TXFRMU[0:31]) 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 to occurring.
