SPI serial data output in SPI slave mode.
(1) Input clock up to 25MHz in SPI slave mode,
(2) output clock at 61KHz in I
(1) Serial data input in SPI slave mode;
(2) serial data input/output in I
Active low.
(1) SPI data transfer start in SPI slave mode. When SPIS_N is
high, the device is deselected and SPIQ is held in high
impedance state, a high-to-low transition to initiate the SPI data
transfer.

Pin Function
LED indicator for Port 2.
Strap option: Switch MAC3 used only.
PU (default) = Select MII interface for the Switch MAC3 SW3-
MII.
PD = Select RMII interface for the Switch MAC3 SW3-RMII.
LED indicator for Port 1.
Strap option: Switch RMII used only.
PU (default) = Select the device as clock mode, when use
RMII interface, all clock source come from pin x1/x2 crystal
25MHz.
PD = Select the device as normal mode when use RMII
interface. All clock source comes from SW4-RMII SM4TXC pin
with an external input 50MHz clock. In the normal mode, the
25MHz crystal clock from pin X1/X2 doesn’t take affect and
should disable SW4-RMII SW4RXC 50MHz clock output by the
register 87.
The normal mode is used when SW4-RMII receive an external
50MHz RMII reference clock from pin SM4TXC.
LED indicator for Port 1.
Strap option: for Switch MAC4 only.
PU (default) = Select MII interface for the Switch MAC4 SW4-
MII.
PD = Select RMII interface for the Switch MAC4 SW4-RMII.
MII management interface clock. Or SMI interface clock
MII management data I/O. Or SMI interface data I/O
Features internal pull down to define pin state when not driven.
Need an external pull-up when driven.
