The RESTORE_USER_ALL command instructs the the TPS544C26 device to copy the entire contents of the non-volatile User Store Memory to the matching locations in the Operating Memory. Any items in Operating Memory that do not have matching locations in the User Store Memory are ignored (for example the STATUS registers). This operation overwrite any value set through a pin detection after the last power-cycle, such as the I2C address set through the I2C_ADDR pin.
Writing a "1" into bit[0] of this command executes the restore operation. When acknowledged, the I2C serial interface is disabled while the restore takes place and all frames will be NACKed during that time. The bit clears itself after the write.
Using the RESTORE_USER_ALL command while the SW switching is enabled is not allowed, meaning a NACK response is provided by the device. RESTORE_USER_ALL command can be executed after the SW switching is disabled.
Return to Supported I2C and Default Values.
