8-bits number_of_bursts
repeat (number_of_bursts)
Note: The starting address is a DWORD address. Appending two 0 bits will form the register address.
As an example, the following is a 3 burst sequence, with 1, 2, and 3 DWORDs starting at register
addresses 40h, 80h, and C0h respectively:
In order to avoid overwriting the Switch CSR register interface or the PHY Management Interface
(PMI), the EEPROM Loader waits until the CSR Busy bit of the
Register (SWITCH_CSR_CMD)
Register (PMI_ACCESS)
The EEPROM Loader checks that the EEPROM address space is not exceeded. If so, it will stop and
set the EEPROM Loader Address Overflow bit in the
address limit is based on the eeprom_size_strap which specifies a range of sizes. The address limit
is set to the largest value of the specified range.
EEPROM Loader Finished Wait-State
Once finished with the last burst, the EEPROM Loader will go into a wait-state and the EPC_BUSY
bit of the
Reset Sequence and EEPROM Loader
In order to allow the EEPROM Loader to change the Port 1/2 PHYs and Virtual PHY strap inputs and
maintain consistency with the PHY and Virtual PHY registers, the following sequence is used:
1. After power-up or upon a hardware reset (nRST), the straps are sampled into the
2. After the PLL is stable, the main chip reset is released and the EEPROM Loader reads the
3. The EEPROM Loader writes select Port 1/2 and Virtual PHY registers, as specified in
Note: Step 3 is also performed in the case of a RELOAD command or digital reset.
