Description

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, Section 4.2.2) is

active, max. gain used during 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, Section 4.2.2) 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.
