Notes on Differences between the Actual MCU and Emulator:
• Operations of the emulator differs from those of flash version MCUs as listed below.
• As a pitch converter board and other devices are used between the evaluation MCU and the target
system, some characteristics are slightly different from those of the actual MCU. Therefore, be sure
to evaluate your system with an evaluation MCU. Before starting mask production, evaluate your
system and make final confirmation with a CS (Commercial Sample) version MCU.
(1) Reset condition
(2) Data values of ROM areas at power-on
(3) Register values when power is turned on
(4) Internal memory (RAM and ROM) capacity, etc.
(5) MCU functions
(6) DBC*, single-step and BRK instruction interrupt vector table addresses
(7) A-D and D-A converter function
Set the time for starting up (0.2 to 0.8 Vcc) 1 µs or less.
When power is turned on, the ROM areas of the emulator are defaulted to 04h.
When power is turned on, the emulator's register values are defaulted to 0. However, the
program counter is defaulted to the reset vector value (E0000h) initially set by the emulator.
Because the internal memories (RAM and ROM) are emulated by the emulation memory, the
capacity and assignment of the emulator's internal memories differ from those of the actual
MCU. For memory mapping, see "4.2 Memory Map" (page 39).
Some MCU functions cannot be used in the emulator system. For details, refer to "Note on
MCU Functions That Cannot Be Used with This Emulator" (page 11).
As the emulator uses the DBC*, single-step and BRK instruction interrupt vector table
addresses, when data is read out from these addresses, the data are different from expected
values.
*1 Interruption for the emulator only
As A-D and D-A converters have a pitch converter board between the evaluation MCU and
the target system, some characteristics are slightly different from those of the actual MCU.
