Figure 34. Send PHY data from TX to RX
In the details of the PD_DATA.Indication message, the “Link Quality Indicator” and the
content of the payload received (either in hexadecimal or string format) can be found.
Note that the PHY layer could generate padding if the amount of data inserted doesn't reach
an acceptable length for the PHY block. This results in additional byte shown in the data
field of the PD-DATA.Indication message. Also note that there's a limit on the amount of data
