Pin Function
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].
Switch or PHY[5] MII management (MIIM registers) data clock. Or
SMI interface clock
Switch or PHY[5] MII management (MIIM registers) 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.
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 KSZ8895MQ/RQ/FMQ/RQ/FMQ is deselected and SPIQ
is held in high impedance state, a high-to-low transition to initiate
the SPI data transfer.
(2) not used in I
Serial bus configuration pin.
For this case, if the EEPROM is not present, the
KSZ8895MQ/RQ/FMQ/RQ/FMQ will start itself with the PS[1.0] =
00 default register values.
