Window COP Mode Bit — When set, a write to the CPMUARMCOP register must occur in the last 25% of the
selected period. A write during the first 75% of the selected period generates a COP reset. As long as all writes
occur during this window, $55 can be written as often as desired. Once $AA is written after the $55, the time-out
logic restarts and the user must wait until the next window before writing to CPMUARMCOP.
the duration of this window for the seven available COP rates.
0 Normal COP operation
1 Window COP operation
COP and RTI Stop in Active BDM Mode Bit
0 Allows the COP and RTI to keep running in Active BDM mode.
1 Stops the COP and RTI counters whenever the part is in Active BDM mode.
Write Mask for WCOP and CR[2:0] Bit — This write-only bit serves as a mask for the WCOP and CR[2:0] bits
while writing the CPMUCOP register. It is intended for BDM writing the RSBCK without changing the content of
WCOP and CR[2:0].
0 Write of WCOP and CR[2:0] has an effect with this write of CPMUCOP
1 Write of WCOP and CR[2:0] has no effect with this write of CPMUCOP.

counter time-out causes a System Reset. This can be avoided by periodically (before time-out) initializing the
COP counter via the CPMUARMCOP register.
While all of the following four conditions are true the CR[2:0], WCOP bits are ignored and the COP operates at
highest time-out period (
(Does not count for “write once”.)
1) COP is enabled (CR[2:0] is not 000)
2) BDM mode active
3) RSBCK = 0
4) Operation in Special Mode
