Pin Function, Note 2-2
LED indicator 0.
Strap option:
PU (default) = Normal mode.
PD = Energy Detection mode (EDPD mode)
Strap to Register 14 bits [4:3]
LED indicator 2.
LED indicator 1.
LED indicator 0.
Strap option:
PU (default) = Select I/O drive strength (8 mA);
PD = Select I/O drive strength (12 mA).
Strap to Register132 bit [7-6].
Digital ground.
3.3V, 2.5V, or 1.8V digital V_DD for digital I/O circuitry.
LED indicator 2.
Strap option for RQX only:
PU (default) = Select the device as clock mode in SW5- RMII,
25MHz crystal/oscillator to X1/X2 pins of the device and pins of
SMRXC and PMRXC output 50 MHz clock.
PD = Select the device as normal mode in SW5-RMII. Switch
MAC5 used only. The input clock from X1/X2 pins is not used, the
device’s clock source comes from SMTXC/SMREFCLK pin which
the 50 MHz reference clock comes from external 50 MHz clock
source, PMRXC can output 50 MHz clock for P5-RMII interface in
the normal mode.
LED indicator 1.
Strap option: for Port 3 only.
PU (default) = Enable auto-negotiation.
PD = Disable auto-negotiation. Strap to Register60 bit [7].
LED indicator 0.
LED indicator 2.
LED indicator 1.
Strap option: for port 3 only.
PU (default) = no force flow control, normal operation.
PD = force flow control. Strap to Register60 bit [4].
LED indicator 0.
Strap option for port 3 only.
PU (default) = force half-duplex if auto-negotiation is disabled or
fails.
PD = force full-duplex if auto negotiation is disabled or fails.
Strap to Register60 bit [5].
PHYs MII management (MIIM registers) data clock. Or SMI inter-
face clock
