The following figure shows the SAMD20 Xplained Pro board connected to PL460-EK expansion
board.
Figure 1-34. SAMD20 Xplained Pro +
PL460-EK
PL460-EK is connected to XPRO Interface connector (EXT1) of SAMD20 Xplained Pro. A 15V DC
jack must be plugged into PL460-EK in order to supply the power for PLC transmission.
For additional information about PL460-EK, refer to the user guide.
PVDD Monitor functionality on this platform requires a change in resistors on PL460-EK to
meet expected voltage levels at ADC input of SAMD20. For such reason, PVDD Monitor is
disabled by means of APP_PLC_DISABLE_PVDDMON macro definition.Figure 1-35. Resistors to Be Replaced on
PL460-EK
The proper resistor values are already configured on MCC for provided projects.Figure 1-36. Resistor Values Configured on
MCC
The USB connector of SAMD20 Xplained Pro can be used to:
Manage the PLC PHY Tx Test
Console. UART baud-rate is configured at 115200 bps (it cannot be higher due to
hardware limitations on this board).
Flash/debug the SAMD20 device
with the on-board J-link debugger.
