Renesas Emulation Pod M30830T-EPB - Manual (Page 16)

IMPORTANT
Note on S/W Break:
• S/W breaks generate break interruptions by forcibly inserting a BRK instruction "08h" instead of
an instruction code. Therefore, when referencing the result of a trace in bus mode, "08h" is
displayed for the instruction fetch address where a S/W break is set.
Note on Differences between Actual MCU and Emulator:
• Operations of the emulator differs from those of mask MCUs as listed below.
(1) Reset condition
(2) Initial values of internal resource data at power-on
(3) Interrupt stack pointer (ISP) after releasing reset
(4) Internal memories (ROM and RAM) capacities, etc.
This emulator system has an MCU with 31KB RAM (0400h - 7FFFh). In single-chip mode
or memory expansion mode, emulation memory for internal flash memory is automatically
allocated in the area between F80000h through FFFFFFh, and it can be read and written into.
(5) Oscillator circuit
• Make note of the fact that in the oscillator circuit where a resonator is connected between
the X
IN
and X
OUT
pins, oscillation does not occur because a flexible cable, buffer IC and other
devices are used between the evaluation MCU and the target system. It is same for sub-clock
oscillators (X
CIN
and X
COUT
).
• For notes on when using the oscillator circuit on the target system, refer to "3.2 (1) Using
the Oscillator Circuit on the Target System" (page 26).
(6) A-D conversion
As a 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.
(7) Port P15
As a part of I/O port (P15) is connected to the target system through the analog switch circuit,
electric characteristics slightly differ from those of an actual MCU.
Notes on Watchdog Function:
• When using the watchdog function, check the box of "Use Watch Dog Timer" in the MCU tab of
the Init dialog box.
• When not using the watchdog function, do not check the box of "Use Watch Dog Timer" in the
MCU tab of the Init dialog box.
• Take note that when the following two conditions are satisfied, programs can not be executed.
(1) The watchdog timer function selection bit (CM06) of the system clock control register 0 is set
to "1".
(2) The HOLD function is used while the watchdog timer is operating.
• If the reset circuit of the target system has a watchdog timer, disable it when using the emulator.
