PHYLASTRCVPKTRSSTATUS

Status returned by the Reed-Solomon decoder on the last received packet (0

- no errors, 1 - corrected errors, 2 or 3 - errors detected but not corrected)

PHYLASTRCVPKTDT

DT value of the last RX PHY packet

PHYLASTRCVPKTPDC

PDC value of the last RX PHY packet

PHYLASTRCVPKTTM

TM value of the last RX PHY packet

PHYFREECHANNELTIME

Timestamp at which the channel becomes free

PHYPREDRIVERGAIN

Correspondence between the attribute value and predriver gain

PHYLASTRXVALIDFCH

FCH of the last valid RX PHY packet

PHYLASTTXFCH

FCH of the last TX PHY packet

PHYAGCRESETTIMEOUT

The number of SYNCP preamble symbols without any preamble detection

after which the AGC is reset

PHYCENELECLEGACYMODE

0 (elementary interleaving, interleaver parameters are not swapped), 1 (full

block interleaving, interleaver parameters are swapped)

PHYRSFILTERDISABLED

Disabled the RS filter: 0 filter active, 1 filter not active

PHYTHRPCS_S

The carrier sense threshold on one SYNCP

PHYTHRPCS_S2

The carrier sense threshold on two SYNCP

PHYPCSWINDOW

The number of SYNCP symbols to wait for the preamble detection after PCS

PHYZCDELAYCOMPENSATION

The delay in µs between the zero crossing of powerline AC and the zero

crossing at the ZC_IN pin. The compensation is applied for phase detection

purposes such as PDC field.
