Field Description
7
Reserved
This field is reserved.
This bit is reserved for future expansion. Software should write 0 to this bit to maintain compatibility.
6–5
RUNM
Run Mode Control
When written, causes entry into the selected run mode. Writes to this field are blocked if the protection
level has not been enabled using the PMPROT register.
NOTE:
RUNM may be set to VLPR only when PMSTAT=RUN. After being written to VLPR, RUNM
should not be written back to RUN until PMSTAT=VLPR.
NOTE:
RUNM may be set to HSRUN only when PMSTAT=RUN. After being programmed to HSRUN,
RUNM should not be programmed back to RUN until PMSTAT=HSRUN. Also, stop mode entry
should not be attempted while RUNM=HSRUN or PMSTAT=HSRUN.
00 Normal Run mode (RUN)
01 Reserved
10 Very-Low-Power Run mode (VLPR)
11 High Speed Run mode (HSRUN)

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 VLLSxor LLSx, the LLSM in the STOPCTRL register is used to further select the
particular VLLSor LLS 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.
000 Normal Stop (STOP)
