Bits 0 - 31: Bytes Transmitted OK Counter (TXBYTEOK[0:31]) 32 bit value indicating the number of bytes
transmitted and determined to be valid. Each time a valid 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 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.
