Peripheral
Mode
Stop2 Stop3
CPU Off Standby
RAM Standby Standby
FLASH Off Standby
Parallel Port Registers Off Standby
ADC Off Optionally On
1
1
Requires the asynchronous ADC clock and LVD to be enabled, else in
standby.
ACMP Off Optionally On
2
2
Requires the LVD to be enabled when compare to internal band-up reference
option is enabled.
BDM Off
3

6
Voltage regulator will be on if BDM is enabled or if LVD is enabled when
entering stop3.
XOSC Off Optionally On
