These registers are used for backing up the POH result during power cycles. At power-up, the POH meter selects the larger of
the two values as the initial count. Incremental results are stored in alternate register pairs. The power-on hour meter may be
reset or preset by writing to these registers. These registers are non-volatile and will be maintained through power and reset
cycles. A valid OEM password is required for access to these registers.

Operation
0: TXDISABLE is not debounced
1: TXDISABLE is debounced. Glitches less than 5 ms are rejected. Set the
bit to 1 is a mechanical switch is used for TXDISABLE. Set to 0 for normal
operation to assure compliance to the SFP MSA.
0: RXLOS low for normal operation and high with a loss of signal condition.
1: RXLOS high for normal operation (signal detected) and low with a loss of
signal (no signal detected) condition.
0: A2 255 (FFh)
1: A2 222 (DEh)
0: Temperature is measured to a resolution of 1ºC
1: Temperature is measured to a resolution of 0.5ºC
0: TXFAULT remains set until TXDISABLE is toggled
1: TXFAULT is in continuous mode and follows the state of the faults.
