Note This command is for multi-processor boards only.
Command Input
NAP MPU#
Options

Description
The NAP command puts an idling CPU into a tight cached loop
from which it will never exit. The napping CPU will not intrude
onto the bus. This command is useful during performance analysis
when it is desirable to allow one single CPU access to the bus
without having to share bus bandwidth with another CPU.
To cause a processor to leave the napping state, a board reset must
be issued.
This command will issue an error message if the system does not
contain two processors.
Example: To ÔnapÕ processor 1, do:
PPC1-Bug>NAP 1<Return>
PPC1-Bug>
