Note on Final Evaluation:
• Watchdog timers cannot be used with this product.
• MCU watchdog timers can only be used during program execution (free running). Disable watchdog timers in
• If the user system has a watchdog timer in its reset circuit, disable it when you use the emulator.
• Since this product uses the internal RAM of the emulator MCU, its RAM size differs from that of the actual
• When the RAM area of the target MCU is larger than the RAM in the emulator MCU, set the marginal area to
• Some registers exceeding 8 bits in length such as the 16-bit timer require that they be read and written to in
• With this emulator, use stack specified by the stack pointer S consume 3 bytes. If there is not enough use stack
• Be sure to evaluate your system and make final confirmation with a CS (Commercial Sample) version MCU.
When setting: Data must be written the lower byte first and then the upper byte.
When you inspect or set these registers, be aware that if one of the following debug operations is performed,
they cannot be inspected or set normally.
In this product, data are read out the lower address first and then the upper address. Since this read byte order
differs from the designated read byte order of the MCU, data cannot be read normally.
When inspecting: Data must be read out the upper byte first and then the lower byte.
(1) Register values are inspected or set in the Dump or the Memory window of the emulator debugger.
(2) Only the upper or the lower byte alone is inspected or set in the emulator debugger before a break.
(3) The instructions to inspect or set these registers are single-stepped in the emulator debugger.
For writes too, since the window is updated after the upper or lower side of a register is set and a read operation
occurs in the middle of a write to the MCU, data cannot be written to the register normally.
In the case of (2) and (3) too, since a read and write to the MCU occurs upon a program break, data cannot be
written to and read out normally.
Please be sure to use the realtime RAM monitor function to verify reads and writes to these registers.
Note that the registers exceeding 8 bits in length which have had their read and write byte sequences designated
include the 16-bit timers (Timer X and Timer Y), the AD conversion register (read-only register), and the
protected registers.
