This field is reserved.
This read-only field is reserved and always has the value 0.

STOPA
Stop Aborted
When set, this read-only status bit indicates an interrupt occured during the previous stop mode entry
sequence, preventing the system from entering that mode. This field is cleared by reset or by hardware at
the beginning of any stop mode entry sequence and is set if the sequence was aborted.
0 The previous stop mode entry was successful.
1 The previous stop mode entry was aborted.
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 STOP, the PSTOPO bits in the STOPCTRL register can be used to select a Partial
Stop mode if desired.

26.4.5 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 and by reset types that
trigger Chip POR. It is unaffected by reset types that do not
trigger Chip POR. See the Reset section details for more
information.
