3 STARTUP AND CONFIGURATION
3.1 Startup
After 3.3 Volt power is applied, the SFP module starts up and self-configures the
88Q2112_A0 transceiver by MDIO interface. This lasts 100ms. Do not apply any I2C
activity on the bus during this time!
3.2 Self-Configuration
The SFP Module configures itself to 1000BASE-T1 after power up. Master-/Slave
Configuration is done according to the DIP switch on the bottom of the device.
To reconfigure the DIP switch the lock has to be opened (see pictures).
ON/right = as Master
OFF/ left = as Slave

3.3 I2C Interface
3.3.1 I2C configuration
100ms after power up of the module it can be configured by I2C.
The module operates with f
The module may clock stretch with f
The module processor listens as slave on the 7-bit address 0x50.
Note: b1010 000X = 0xA0
Read access beyond address 95 will return 0x00.
The 88Q2112_A0 transceiver can be accessed at I2C slave 7-bit address 0x40.
Note: b1000 000X = 0x80
The 88Q2112_A1 PHY does not support I2C interfaces. However, the microcontroller
acts as a bridge between the host and the PHY. Commands from the Host are
processed by the microcontroller. The microcontroller accesses to the PHY trough
MDIO interface and forwards the information to the Host.
For a complete register map please have a look at the 88Q2112_A1 datasheet (NDA
required).

3.3.3 I2C Device addressing and operation
3.3.3.1 I2C Current address read
The current read operation only requires the device address read word to be sent.
When the acknowledge is received from the SFP module, the current address data
word is serially clocked out.
100BASE-T1 MediaConverter_BCM User Manual
12
Example: Read the current address of the SFP module (b1010000X).
3.3.3.2 Random address read
The random address read requires two operations to perform the read.
Example: Read a random address of the SFP module (b1010000X)
First a write operation to specify the address desired to read:
100BASE-T1 MediaConverter_BCM User Manual
13
Then a read operation to read the previous address specified:
3.3.3.3 Sequential read
The sequential reads are started by either a current word address read or a random
address read. To specify a sequential read, the host responds with an acknowledge
instead of a stop after each data word.
First a write operation to specify the address desired to read:
100BASE-T1 MediaConverter_BCM User Manual
14
Then the read operations:
3.3.3.4 Byte Write
The write operation requires 8-bits of data word address following the device address
write word and acknowledgement.
Example: Byte write operation into the SFP module (b1010000X)
3.3.3.5 Sequential write
The sequential write is started in the same way as a single byte write, but the host
master does not send a stop condition after the first word is clocked in.

3.3.4 I2C access to the 88Q2112_A0 transceiver
The 88Q2112_A0 PHY listens as slave on the 7-bit address 0x40. Every internal register
of the PHY (16 bits) is accessed by defining the Device Number (1 byte) and the
Register address (2 bytes). The I2C Memory address is mapped as:
0x00 Device number
0x01 Register_address_MSB
0x02 Register_address_LSB
0x03 PHY_Register_Operation_Status
0x04 PHY_Register_data_MSB
0x05 PHY_Register_data_LSB
Table 3-2: Register addresses
3.3.4.1 Register description
• Device number:
Defines the device number of the register to access
• Register_address_MSB:
Defines the Most significant byte of the register to access
• Register_address_LSB:
Defines the Less Significant Byte of the register to access
• PHY_Register_Operation_Status
o Bit 0 – Read Start Condition Flag (Read/Write)
This flag is set by the master after specifying the first 3 bytes of the register
(Devices number, Register_address_MSB and Register_address_LSB) when a
read operation is trigged.
o Bit 1 – Read In Progress Flag (Read)
This flag is set by the slave during the reading operation
o Bit 2 – Read Operation Done Flag (Read)
This flag is set by the slave when the reading operation is finished. This flag can
be read after triggering the read to ensure that the data has finished reading.
100BASE-T1 MediaConverter_BCM User Manual

o Bit 3 – Write Start Condition Flag (Read)
This flag is set by the slave when a write operation is trigged.
o Bit 4 – Write In Progress Flag (Read)
This flag is set by the slave during the writing operation
o Bit 5 – Write Operation Done Flag (Read)
This flag is set by the slave when the writing operation is finished. This flag can
be read after writing the PHY_register_data_LSB to ensure that the data has
finished writing
• PHY_register_data_MSB
When a reading operation, this register contains the MSB of the PHY register. When
a write operation, this register contains the MSB to write in the PHY register
• PHY_register_data_LSB
When a reading operation, this register contains the LSB of the PHY register. When
a write operation, this register contains the LSB to write in the PHY register
