Bits 31 to 0: All Bytes Transmitted Counter (TXBYTEC31 to TXBYTEC0). 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 rollover occurring.
