Register access aborted (Error 630)
Cause: Occurs when a <CTRL> c is entered during register display.
Register class cannot be modified: <register class> (Error 637)
Cause: You tried to modify a register class instead of an individual register. You
can only modify individual registers.
Action: See the display and modify syntax pages in Chapter 11,
"Emulator/Analyzer Interface Commands", in this manual for a list of register
names.
Register emmbar=000000000H; valid bit not set (Error 149)
Cause: You entered a command to copy the values of the EMSIM register set into
the target SIM registers. The EMSIM register set can be copied into the processor
SIM set only when register emmbar is valid (that is, the valid bit of emmbar, bit 0,
must equal 1).
Action: Write a valid content into emmbar and set emmbar bit 0=1. Then try your
command again.
Register mbar=000000000H; valid bit not set (Error 149)
Cause: You entered a command that must access the SIM register set. The SIM
register set can only be accessed when register mbar is valid (that is, the valid bit of
mbar, bit 0, must equal 1).
Action: Write a valid content into mbar and set mbar bit 0=1. Then try your
command again.
Request access to guarded memory: <address> (Error 707)
Cause: The address or address range specified in the command included addresses
within a range mapped as guarded memory. When the emulator attempts to access
these during command processing, the above message is printed, along with the
specific address or addresses accessed.
Action: Reenter the command and specify only addresses or address ranges within
emulation or target RAM or ROM. You can also remap memory so that the desired
addresses are no longer mapped as guarded.
