Configuration
The VSC8641 device can be configured using three different methods:
•
•
•
Registers
This section provides information about how to configure the VSC8641 device using its
internal memory registers and the management interface. For information about
configuring the device using the CMODE pins, see
about setting up an external EEPROM to perform startup configuration, see
page 70.
The following illustration shows the relationship between the device registers and their
address spaces.
