GPIO SIGNAL HEADERS
Refer to the board schematics in
Appendix B. “EVB-KSZ8563 Schematics”
and the
KSZ8563 Data Sheet
for further details and usage on the GPIO signal pins.
2.5.5
INTRP_N Output
The INTRP_N output at test point TP14 provides the interrupt output from the KSZ8563
device. By default, it is active low and drives low to turn on D4 when asserted.
Refer to board schematics in
Appendix B. “EVB-KSZ8563 Schematics”
and
KSZ8563 Data Sheet
for further details and usage on the INTRP_N signal.
2.5.6
PME_N Output
The PME_N output at test point TP16 provides the Power Management Event (PME)
interrupt output for Wake-on-LAN (WoL) from the KSZ8563 device. By default, it is
active low and drives low to turn on D5 when asserted.
Refer to the board schematics in
Appendix B. “EVB-KSZ8563 Schematics”
and the
KSZ8563 Data Sheet
for further details and usage on the PME_N signal.

USING THE EVB-KSZ8563
The EVB-KSZ8563 plugs in directly to a mating Microchip host controller or processor
board, such as the SAMA5D3-EDS Board, that delivers full power and provides full reg-
ister access and configuration via IBA, SPI, or I
2
C bus management.
Together, the EVB-KSZ8563 and the SAMA5D3-EDS enable Ethernet traffic switching
across all three data ports of the KSZ8563 device with RGMII MAC port 3 connecting
to the SAMA5D3 processor and PHY ports 1 and 2 connecting via copper Ethernet
cable (CAT-5 UTP or better) to external Ethernet devices.
All KSZ8563 registers are accessible via IBA, SPI, or I
2
C bus management from the
SAMA5D3-EDS Board, enabling full evaluation and firmware development for all
KSZ8563 MAC/Switch features and interaction with upper network layers.
Refer to SAMA5D3-EDS Board documentation on its usage.
