Bits 0 - 31: All Bytes Transmitted Counter (TXBYTEC[0:31]) 32 bit value indicating the number of bytes
transmitted. Each time a byte is transmitted, 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 data 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.
