SPI/I2C/MIIM Interface Pins

SPI/I2C/MIIM

Serial Clock

SCL/MDC

IPU

SPI/I2C Modes: SCL serial clock.

MIIM Mode: MDC serial clock.

SPI Data Out

SDO

SPI Mode: Data out (also known as MISO).

I2C/MIIM Modes: Not used.

SPI Data In /

I2C/MIIM Data

In/Out

SDI/SDA/MDIO

IPU/O8

SPI Mode: SDI Data In (also known as MOSI).

I2C Mode: SDA Data In/Out.

MIIM Mode: MDIO Data In/Out.

SDI and MDIO are open-drain signals when in the output

state. An external pull-up resistor to VDDIO (1.0kΩ to

4.7kΩ) is required.

SPI Chip Select

SCS_N

IPU

SPI Mode: Chip Select (active low).

I2C/MIIM Modes: Not used.
