Bits 0 to 31: All Frames Aborted Counter (TXFRMBD[0:31]) 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 roll-over to occurring.
