Command Brief Description
Non-Volatile
Memory Storage
16 RESTORE_USER_ALL
Restores all of the storable register settings from the non-volatile memory
(EEPROM). The command should not be used while the device is actively
switching
19 CAPABILITY
This command helps the host system/GUI/CLI determine key capabilities of the
module
Format Unsigned Binary
Bit Position 7 6 5 4 3 2 1 0

Function Mantissa
Default Value 0 0 0 1 0 0 0 1
Exponent -2 (dec), fixed
Mantissa
The upper four bits are fixed at 0
The lower seven are programmable with a default value of 9(dec). This
corresponds to a default of 4.25V. Allowable values are
• 4.25, in steps of 0.25V upto 9.5V.
• 9.5V to 13V in increments of 0.5V
• 13V to 16V in increments of 1V
YES
