EEPROM Options for MODE SELECT Defaults

As shown in Table A-1, many EEPROM options allow you to specify

the power-on defaults for various fields in the MODE SELECT

command. These power-on defaults can be overridden by issuing a

MODE SELECT command at any time during CTS operation.

Note: The options in Table A-1 are arranged in MODE SELECT Page

Code order. (For example, options for Page Code 01h are

listed before options for Page Code 20h.)
