The SYS_CONFIG1 (A0h) register contains common settings such as enabling forced CCM and selecting how the output voltage is programmed. To write new settings, switching must first be disabled either through the EN pin or through OPERATION. See Section 5.2 for details on different options to enable and disable switching. If switching is enabled, the TPS544C26 NACKs. The new setting takes effect when switching is enabled again.
