Pin No
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.
ADDRESS
These pins are used to select a register or memory.
Address pins are internally pulled down.
DATA
These pins are used to read and write register or
memory data.
CHIP SELECT
Chip Select is for MCU to access to internal registers or
memory. /WR and /RD select direction of data transfer.
This pin is active low.
INTERRUPT
This pin Indicates that W5100 requires MCU attention
after socket connecting, disconnecting, data receiving or
timeout. The interrupt is cleared by writing IR(Interrupt
Register) or Sn_IR (Socket nth Interrupt Register). All
interrupts are maskable. This pin is active low.
WRITE ENABLE
Strobe from MCU to write an internal register/memory
selected by ADDR[14:0]. Data is latched into the W5100
on the rising edge of this input. This signal is active low.
READ ENABLE
Strobe from MCU to read an internal register/memory
selected by ADDR[14:0]. This signal is active low.
SPI ENABLE
This pin selects Enable/disable of the SPI Mode.
Low = SPI Mode Disable
