Configuration
The VSC8601 device can be configured using three different methods:
•
•
•
Setting internal memory registers using the management interface.
Setting a combination of CMODE pins and registers.
Loading a configuration into an external EEPROM and connecting that device so that
it writes configuration information at system startup.

Registers
This section provides information about how to configure the VSC8601 device using its
internal memory registers and the management interface. For information about
configuring the device using the CMODE pins, see “CMODE,” page 64. For information
about setting up an external EEPROM to perform startup configuration, see “EEPROM,”
page 66.
The following illustration shows the relationship between the device registers and their
address spaces.
