Pin No.
Pin No.
Collision LED : Active low when collisions occur.
Transmit activity LED : Active low indicates the
presence of transmitting activity.
Receive activity LED : Active low indicates the
presence of receiving activity.
Full Duplex LED : Active low when in full duplex
operation. Active high when in half duplex
operation.
Link LED : Active low in link state indicates a
good status for 10/100M.
It is always ON when the link is OK and
while in a TX or RX state.
Interrupt : Active low
After reception or transmission it indicates that
the W5100 requires MCU attention.
By writing values to the Interrupt Status Register
of W5100 the interrupt will be cleared.
All interrupts can be masked by writing values to
the IMR of W5100 (Interrupt Mask Register).
For more details refer to the W5100 Datasheet
Reset : This pin is active low input to
initialize or re-initialize W5100.
By asserting this pin low for at least 2us,
all internal registers will be re-initialized
to their default states.
SPI
Enable/Disable W5100 SPI Mode.
A pull-down resistor(R10) sets to the
default of SPI Mode Disable.
H/W ver.1.0 : R10 is not mounted
H/W ver.1.1 : R10 is mounted
Not Connect
Low = SPI Mode Disable
High = SPI Mode Enable
