default value

0 – 1

Max. temp.

Max. temperature reached during PHY frame transmission.

0: T < 70 °C (typical)

1: 70 °C < T < 100 °C (typical)

2: 100 °C < T < 125 °C (typical)

3: T > 125 °C (typical)

2 – 6

Max. gain

If current control feature (MIB object PHY Config 01h, Table 54)

is active, max. gain used during the last transmission. If current

control feature is not active, gain used during last transmission.

Unused

0 – 1

Min. temp

Min. temperature reached during PHY frame transmission.

0: T < 70 °C (typical)

1: 70 °C < T < 100 °C (typical)

2: 100 °C < T < 125 °C (typical)

3: T > 125 °C (typical)

2 – 6

Min. gain

If current control feature (MIB object PHY Config 01h, Table 54)

is active, min. gain used during last transmission. If current

control feature is not active, gain used during last transmission.

Unused

0 – 6

Overcurrent

events number

Number of overcurrent events reached during PHY frame

transmission. Valid if the current control feature is active only.

Overcurrent

notification

Notification about the overcurrent reached during last

transmission. Valid whether the current control is active or not.

0: max. output current [·] value not reached

1: max. output current [·] value reached

3 - 4

ZC Delay

Delay between the last transmitted UW last bit and the mains

zero-crossing (signed value), expressed in 13 µs step
