Serial Data Line (SDA). I2C serial data line. Bi-directional. This bus
reads from and writes into the S19252 control logic.
Serial Clock Line (SCL). I2C serial clock line.This pin is used as
I2C serial clock line (SCL) when MODE[2:0] = 001.
Reserved address Line. This address bit is used to uniquely iden-
tify each S19252 device MDIO interface mode if multiple S19252
devices are controlled by a single microprocessor and MODE[2:0] =
000.
Management Data Control Input/Output Bus. Bi-directional 2-wire
bus for efficient control. This bus reads from and writes into most of
the S19252 control logic when MODE[2:0] = 000.
This pin is used as SDI input signal in the SPI serial interface when
MODE[2:0] = 010.
Management Clock Control Input. Clock for Bi-directional MDIO
bus when MODE[2:0] = 000.
This pin is used as SCK input signal in the SPI serial interface when
MODE[2:0] = 010.
Reserved address Line. This address bit is used to uniquely iden-
tify each S19252 device for MDIO interface mode if multiple S19252
devices are controlled by a single microprocessor when MODE[2:0]
= 000.
This pin is used as SDO output signal in the SPI serial interface
when MODE[2:0] = 010.
Reserved address Line. This address bit is used to uniquely iden-
tify each S19252 device for MDIO and I2C interface modes if multi-
ple S19252 devices are controlled by a single microprocessor when
MODE[2:0] = 000 or 001.
This pin is used as CS input signal in the SPI serial interface when
MODE[2:0] = 010.
Reserved address Line. This address bit is used to uniquely iden-
tify each S19252 device for MDIO and I2C interface modes if multi-
ple S19252 devices are controlled by a single microprocessor.
Reserved address Lines. These address bits are used to uniquely
identify each S19252 device for MDIO and I2C interface modes if
multiple S19252 devices are controlled by a single microprocessor.
Operating Mode Selection Control. These inputs configure the
operation mode for the S19252. When these inputs all pulled down,
the serial communication is configured as MDIO. See Table 15 and
16 for further info.
