IMPORTANT
Note on exception handling:
z
Because the compact emulator emulates several target MCUs with a single evaluation MCU, the exception
handling factors of the actual MCU and those of the evaluation MCU are not always the same. Use only
exception handling factors which the hardware manual describes that it is available.
In addition, the low-voltage detection interrupt that an evaluation MCU does not have and the exception
handling related to an on-chip oscillator are not supported.
Note on the I/O registers:
z
Since the compact emulator emulates several target MCUs using a single evaluation MCU, the I/O registers of
the actual MCU and those of the evaluation MCU are not always the same. Therefore, do not access the
reserved I/O registers of the target MCU. Note also that accesses to the registers listed below that are associated
with power-on reset & low-voltage detection circuit functions, on-chip oscillator and flash memory control are
invalid.
-
Low-voltage-detection Control Register (LVDCR: H’F730)
-
Low-voltage-detection Status Register (LVDSR: H’F731)
-
Reset Source Decision Register (LVDRF: H’F732)
-
Clock Control/Status Register (CKCSR: H’F734)
-
RC Control Register (RCCR: H’F735)
-
RC Trimming Data Protect Register (RCTRMDPR: H’F736)
-
RC Trimming Data Register (RCTRMDR: H’F737)
-
Flash Memory Control Register 1 (FLMCR1: H’FF90)
-
Flash Memory Control Register 2 (FLMCR2: H’FF91)
-
Flash Memory Power Control Register (FLPWCR: H’FF92)
-
Block Specification Register 1 (EBR1: H’FF93)
-
Flash Memory Enable Register (FENR: H’FF9B)
For details, refer to notes on each MCUs in “Notes on Using This Product (2)” (page 75).
Note on Clock Supply to the MCU:
z
A clock supplied to the evaluation MCU is selected by the Clock tab in the Init dialog box of the emulator
debugger.
(1) When "Internal" is selected:
A clock generated by the oscillation circuit in the emulator is supplied to the evaluation MCU. The clock is
continually supplied to the evaluation MCU regardless of a status of user system clock and a status of user
program execution.
(2) When "External" is selected:
Clock supply to the evaluation MCU depends on oscillation state (oscillate/off) of the user system.
Notes on Software Breaks:
z
Software breaks change the instruction at a specified address to a BRK (H’5770). Therefore, take note that
when you reference the result of a trace in bus mode, " H’5770" is displayed.
z
As the BRK instruction is used for the emulator, do not use it in a user program.
