Description
STOPM
Stop Mode Control
When written, controls entry into the selected stop mode when Sleep-Now or Sleep-On-Exit mode is
entered with SLEEPDEEP=1 . Writes to this field are blocked if the protection level has not been enabled
using the PMPROT register. After any system reset, this field is cleared by hardware on any successful
write to the PMPROT register.
NOTE: When set to VLLSx, the VLLSM bits in the STOPCTRL register is used to further select the
particular VLLS submode which will be entered.
NOTE: When set to STOP, the PSTOPO bits in the STOPCTRL register can be used to select a Partial
Stop mode if desired.

13.3.3 Stop Control Register (SMC_STOPCTRL)
The STOPCTRL register provides various control bits allowing the user to fine tune
power consumption during the stop mode selected by the STOPM field.
NOTE
This register is reset on Chip POR not VLLS and by reset types
that trigger Chip POR not VLLS. It is unaffected by reset types
that do not trigger Chip POR not VLLS. See the Reset section
details for more information.

PSTOPO
Partial Stop Option
These bits control whether a Partial Stop mode is entered when STOPM=STOP. When entering a Partial
Stop mode from RUN mode, the PMC, MCG and flash remain fully powered, allowing the device to
wakeup almost instantaneously at the expense of higher power consumption. In PSTOP2, only system
