XRT94L33
Rev.1.2.0.
STEP 2b – Set Bits 0 through 4 (“Tx_UTOPIA_Addr[4:0]”) within the “Transmit UTOPIA Address”
Register to the desired “Multi-PHY” Address value for this channel [b4, b3, b2, b1, b0]; as depicted
below.
Transmit UTOPIA Address Register (Address = 0x0593)
This step configures the Transmit UTOPIA Address, of the value [B4, B3, B2, B1, B0] to be assigned to
Channel 1.
Notes:
Once the user has executed STEPS 2a and 2b, then STS-3c Channel 1 within the XRT94L33 has been
assigned the “Transmit UTOPIA Address” of [b4, b3, b2, b1, b0].
STEP 3 – Assign a “Transmit UTOPIA Address” to STS-3c Channel 2
The user can accomplish this by doing the following.
STEP 3a – Set Bits 0 through 4 (“Tx_UTOPIA_Port_Number[4:0]”) within the “Transmit UTOPIA Port
Number Register” to “0x02”; as depicted below.
Transmit UTOPIA Port Number Register (Address = 0x0597)
This step configures an internal “Transmit UTOPIA Address assignment” pointer to point to “STS-3c Channel
2” within the XRT94L33.
STEP 3b – Set Bits 0 through 4 (“Tx_UTOPIA_Addr[4:0]”) within the “Transmit UTOPIA Address”
Register to the desired “Multi-PHY” Address value for this channel [c4, c3, c2, c1, c0]; as depicted
below.

During this step, the user can write in any value, between 0x00 and 0x1E, provided this “Multi-PHY Address” is
unique among all of the Transmit UTOPIA Addresses within a “Multi-PHY” system.
Use of the value “0x1F” is NOT permitted.
These steps do not assign a Receive UTOPIA Address value to STS-3c Channel 1. This assignment must be
performed separately per the “Receive UTOPIA Address Assignment” instructions presented in Section _.
