H8S, H8SX Family E10A-USB Emulator
4. The emulator communicates with the MCU by using the P34/TRST#, P37/TCK, P35/TMS,
P63/TDO, and P36/TDI pins. These pins cannot be used.
5. The power consumed by the MCU can reach several mA. This is because the user power
supply drives ICs to make the communication signal level match the user-system power-
supply voltage.
6. Do not use an MCU that has been used for debugging.
If the flash memory is reprogrammed many times, and the MCU is left for a few days, data
may be lost due to retention problems.
If the flash memory is reprogrammed many times, the data will not be erased. If an error
message is displayed, exchange the MCU for a new one.
7. MCU Operating Mode
Use the emulator in mode 3 (single-chip mode).
8. Sum Data Displayed in the Program Flash Mode
Sum data, which is displayed in the 'Program Flash' mode, is a value that data in the whole
internal ROM areas has been added by bytes.
9. Note on Executing the User Program
The set value is rewritten since the emulator uses flash memory and watchdog timer registers
during programming (Go, Step In, Step Out, or Step Over) of the flash memory.
10. Note on Reprogramming the Flash Memory
While the flash memory is reprogrammed during Go operation, actual reprogramming will not
be performed if the flash memory is reprogrammed on the [Memory] window. Therefore, the
contents will not be displayed correctly on the [Memory] window.
11. Value Set in the [System Clock] Dialog Box when Connecting the Emulator
Input the frequency of the oscillator in use in the [System Clock] dialog box (this also applies
when the MCU is multiplied by the PLL circuit).
