Pin No.
SCLK(Serial Clock)
This pin is used to SPI Clock Signal pin.
/SCS (Slave Select) *
This pin is used to SPI Slave Select signal Pin.
This pin controls SPI_EN signal of W5100. When
/SCS signal assert low, W5100 drive SPI mode by
SPI_EN signal toggled high.
MOSI (Master Out Slave In) *
This pin is used to SPI MOSI signal pin.
MISO (Master In Slave Out) *
This pin is used to SPI MISO signal pin.
Address
Used as Address[14-8] pin
Address
Used as Address[7-0] pin
Data
8 bit-wide data bus
Module Select : Active low.
/CS of W5100
Read Enable : Active low.
/RD of W5100
Write Enable : Active low
/WR of W5100
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).
