Notes
1. The MSB of the POR/Soft Reset value is marked as ‘y’: the default value of the POR bit is set after Power-on
reset (POR value = 1000 0000). However it will be cleared after a SBC Soft Reset command (Soft Reset value =
0000 0000).
2. During Sleep Mode, the bits VCC1_SC,VCC1_OV and VCC1_UV will not be set when VCC1 is off
3. The VCC1_UV bit is never updated in SBC Restart Mode, in SBC Init Mode it is only updated after RO was
released for the first time, it is always updated in SBC Normal and Stop Mode, and it is always updated in any
SBC modes in a VCC1_SC condition (after VCC1_UV = 1 for >4ms).
