Bits 31 to 0: All Frames Aborted Counter (TXFRMBD31 to TXFRMBD0). 32-bit value indicating the number of
frames aborted due to any reason. Each time a frame is aborted, 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.
