9. Loading Sessions
Information in [JTAG clock] of the [Configuration] dialog box cannot be recovered by loading
sessions. Thus the TCK value will be 2.5 MHz.
10. [IO] Window
⎯ Display and modification
For each watchdog timer register, there are two registers to be separately used for write and
read operations.
Table 3.4 Watchdog Timer Register
Register Name Usage Register
WTCSR (W) Write Watchdog timer control/status register
WTCNT (W) Write Watchdog timer counter
WTCSR(R) Read Watchdog timer control/status register
WTCNT(R) Read Watchdog timer counter
After the I/O-register definition file is created, the MCU’s specifications may be changed.
If each I/O register in the I/O-register definition file differs from addresses described in the
hardware manual, change the I/O-register definition file according to the description in the
hardware manual. The I/O-register definition file can be customized depending on its
format. Note that, however, the emulator does not support the bit-field function.
⎯ Verify
In the [IO] window, the verify function of the input value is disabled.
11. Illegal Instructions
Do not execute illegal instructions with STEP-type commands.
12. MCU Operating Mode
Do not use the emulator in the boot, user boot, and user program modes.
13. Internal Flash Memory
It is not possible to reprogram the content of the internal flash memory during execution of the
user program.
