PMBus Command Description
Operation, Mode and EEPROM Commands
PAGE
The LTC2978 has eight pages that correspond to the eight DC/DC converter channels that can be managed. Each DC/DC
converter channel can be uniquely programmed by first setting the appropriate page.
The PAGE command provides the ability to configure, control and monitor multiple outputs on one unit.
Setting PAGE = 0xFF allows a simultaneous write to all pages for PMBus commands that support global page programming.
The only commands that support PAGE = 0xFF are OPERATION and ON_OFF_CONFIG. See MFR_PAGE_FF_MASK for
additional options. Reading any paged PMBus register with PAGE = 0xFF returns unpredictable data and will trigger
a CML fault.
