83
Stack is in emulation ROM
Cause: Your stack pointer pointed to a location in memory mapped as emulation
ROM; you then attempted to run or step the emulation processor. The emulator
was unable to access the stack to complete the transition from the monitor to the
user program or vice versa.
Action: Either remap memory so the stack pointer points to a location in RAM, or
change the stack pointer value (either with your program or by configuring the
emulator's stack pointer value on reset) to point to a location in RAM.
84
Program counter is odd
Cause: You attempted to modify the program counter to an odd value using the
modify registers command on a processor which expects even alignment of
opcodes.
Action: Modify the program counter only to even numbered values.
102 Monitor failure; no clock input
Cause: The monitor is unable to run because no emulation processor clock is
available.
Action: If running out of circuit, select the internal clock during configuration; if
running in-circuit, select the external clock during configuration and make sure a
clock meeting the microprocessor's specifications is input to the clock pin of the
target system probe.
103
Monitor failure; no processor cycles
Cause: The monitor is unable to run since the processor is not running. The
monitor is unable to determine the cause of the failure.
Action: If running in-circuit, troubleshoot the target system. If running out of
circuit, reinitialize the emulator and try the procedure again.
104 Monitor failure; bus grant
Cause: The monitor is unable to run. The emulation processor is not running
because it has granted the bus to another device.
Action: Wait until the processor has regained bus control, then retry the operation.
