Field
Description
PDO
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 STOP mode, only pad power sequence driver is disabled but
the state of the output is kept. In STANDBY mode, power sequence driver and all pads except those mapped
on wakeup lines are not powered and therefore high impedance. Wakeup line configuration remains
unchanged.
MVRON
Main voltage regulator control — This bit specifies whether main voltage regulator is switched off or not while
entering this mode.
0 Main voltage regulator is switched off
1 Main voltage regulator is switched on
DFLAON
Data flash power-down control — This bit specifies the operating mode of the data flash after entering this
mode.
00 reserved
01 Data flash is in power-down mode
10 Data flash is in low-power mode
11 Data flash is in normal mode
CFLAON
Code flash power-down control — This bit specifies the operating mode of the program flash after entering
this mode.
00 reserved
01Code flash is in power-down mode
10Code flash is in low-power mode
11Code flash is in normal mode
FMPLL1ON secondary frequency modulated phase locked loop control
0 secondary frequency modulated phase locked loop is switched off
1 secondary frequency modulated phase locked loop is switched on
FMPLL0ON primary frequency modulated phase locked loop control
0 primary frequency modulated phase locked loop is switched off
1 primary frequency modulated phase locked loop is switched on
FXOSCON fast external crystal oscillator (4-16MHz) control
0 fast external crystal oscillator (4-16MHz) is switched off
1 fast external crystal oscillator (4-16MHz) is switched on
