Description
I/O output power-down control — This bit controls the output power-down of I/Os.
0 No automatic safe gating of I/Os used and pads power sequence driver is enabled
1 In SAFE/TEST modes, outputs of pads are forced to high impedance state and pads power
sequence driver is disabled. The inputs are level unchanged. In STOP0 mode, only the pad power
sequence driver is disabled, but the state of the output remains functional.
Main voltage regulator control — This bit specifies whether main voltage regulator is switched off
or not while entering this mode.
1 Main voltage regulator is switched on
Flash power-down control — This bit specifies the operating mode of the code flash after entering
this mode.
00 reserved
01 Flash is in power-down mode
