RUN - MPU Execution/Status

3-206

Descriptions of all possible states:

Note The debugger only permits one processor to execute

the debugger monitor. This is achieve by placing a

semaphore prior to the exception handler access. The

stalled processor will wait indefinitely. The

current/master processor must be idled, forked, or

executed (GO, GT, GN, GD commands) before the

stalled processor is serviced.

State Description

IDLE Processor is idle (can be forked).

UNKNOWN Processor never became idle from start up

(power-up/reset).

EXECUTING TARGET Processor has been forked to target code.

ERROR Illegal state.

EXCEPTION PROCESSING PENDING Processor is stalled at the exception handler

semaphore (see NOTE).
