Extension Mode 2
• The memory reference commands are added, which reference the internal ROM in the bank
duplicated area in the dump format (see the table below).
A memory reference command with the bank specification is added. The memory reference/the
change to the bank repetition area must use the following commands.
Command name Abbreviation

DumpWord2 DW2
DumpLword2 DL2
SetMemoryByte2 MB2
SetMemoryWord2 MW2

• The following emulator functions are implemented by analyzing the bus information (address bus,
data bus).
- RAM monitor function (RAM Monitor window, C Watch window)
- Coverage measurement function (Coverage window, Coverage command)
- Memory protect function (Protect window, Protect command)
- Hardware event (H/W break event*, Real-time trace event*, Time measurement event)
MCU switches the bank to be accessed based on the value in the bank selection register. A signal
which can distinguish which bank accesses the bus information is not output. Therefore, the
above function may work as expected.
*By specifying Simultaneous And (AND logic) (same time) for the hardware event and the bank
selection register, both of which are detected as the combined condition in the State Transient
Break/Trace window, the hardware event for the bank duplicated area can be detected.
• If you use the Memory Reference/Change command for the bank duplicated area before MCU is
switched from the normal mode to the memory space expansion mode 2 by the target program,
the function may not work as expected.
• The memory map shows the following data after the debugger gets started.
