Description
Sleep or Deep-Sleep Power Request Active
Value Description
0 A power request is not active.
1 The microcontroller is currently in Deep-Sleep mode or is in
Sleep mode and a request to put the SRAM and/or Flash
memory into a lower power mode is currently active as
configured by the SLPPWRCFG register.

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
PIOSC Power Down Request Warning
Value Description
0 No error.
1 A warning has occurred because software has requested that
the PIOSC be powered down during Deep-Sleep using the
PIOSCPD bit in the DSLPCLKCFG register and a peripheral
requires that it be active in Deep-Sleep. The PIOSC is powered
down regardless of the warning.
0
VLDO Value Above Maximum Error
Value Description
0 No error.
1 An error has occurred because software has requested that the
LDO voltage be above the maximum value allowed using the
VLDO bit in the LDOSPCTL or LDODPCTL register.
In this situation, the LDO is set to the factory default value.
0
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
0
VLDO Value Below Minimum Error in Sleep Mode
Value Description
0 No error.
1 An error has occurred because software has requested that the
LDO voltage be below the minimum value allowed using the
VLDO bit in the LDOSPCTL register.
In this situation, the LDO voltage is not changed when entering
Sleep mode.
