Description
Switch MII receive data valid
Strap option: MII mode selection
PU = PHY mode.
PD = MAC mode
MLL/FLL: Switch MII receive data bit 3/
RLL: Output reference clock in RMII mode.
Strap option: enable auto-negotiation on port 2 (P2ANEN)
PU = enable
PD = disable
Switch MII receive data bit 2
Strap option: Force the speed on port 2 (P2SPD)
Switch MII receive data bit 1
Strap option: Force duplex mode (P2DPX)
negotiation fails. Force port 2 in full duplex mode if P2ANEN = 0.
auto-negotiation fails. Force port 2 in half duplex mode if P2ANEN = 0.
Digital ground
Switch MII receive data bit 0
Strap option: Force flow control on port 2 (P2FFC)
negotiation result.
MLL/FLL: Switch MII carrier sense
RLL: No connection, Internal pull up.
MLL/FLL: Switch MII collision detect
RLL: No connection, Internal pull up.
MLL/FLL: Switch MII receive clock.
RLL: No Connection.
Digital ground
Ferrite bead and capacitor.
SPI slave mode: serial data output
Note: an external pull-up is needed on this pin when it is in use.
Strap option: XCLK Frequency Selection
PU = 25 MHz
PD = 50 MHz
When SPISN is high, the KSZ8873MLL/FLL/RLL is deselected and SPIQ
is held in high impedance state.
A high-to-low transition is used to initiate SPI data transfer.
Note: an external pull-up is needed on this pin when it is in use.
1.8 digital VDD input power supply from VDDCO (pin 58) through external
SPI slave mode: chip select (active low)
PD = force port 2 to 10BT if P2ANEN = 0
PU = port 2 default to full duplex mode if P2ANEN = 1 and auto-
PU = always enable (force) port 2 flow control feature.
PU = force port 2 to 100BT if P2ANEN = 0
PD (default) = Port 2 default to half duplex mode if P2ANEN = 1 and
PD = port 2 flow control feature enable is determined by auto-
Output in PHY MII mode
Input in MAC MII mode
