Caution
W hen using nanoEASE connecting with ML610QXXX on your target
Board, VDDL on ML610QXXX has to be connected to corresponding
terminals of nanoEASE user cable only. Do not forget to isolate other
VDDL supply from your target board. Otherwise, not only nanoEASE
broken, but also burst and / or fire or electric component may be
caused.

The length of the cable (nanoEASE interface cable) which connects a user target system with nanoEASE is
about 15cm. A nanoEASE interface connector should be located as much as possible in the end of PCB,
and please arrange it so that wiring with a nanoEASE interface connector and ML610Qxxx serves as the
shortest.

1.3 Notes
The notations of debugging or programming by using the nanoEASE are shown below.
1.3.1 Notes for on-chip debug emulator
■ A RAM data match break
- When the RAM data match break occurs, the emulation is stopped after the CPU executes until 3
instructions from the satisfied of break condition.
■ Any break functions
As following, the behavior of the ML610Qxxx is influenced by break functions. Therefore, do not use the
break function during the final check of application programs.
-When the break occurred, the following peripherals of ML610Qxxx are stopped.
¾ LTBC
¾ Real-time clock
¾ 1kHz timer
¾ Timer 0/1/2/3
¾ Watch dog timer
¾ Melody driver
If peripherals are enabled, the behavior will restart when the emulation is started.
- When the interruption occurs in the break, the CPU defers the execution of each interruption handler
to the next emulation.
- If you use the force break function when CPU is STOP/HALT mode, the STOP/HALT mode is
released by the break. And, if you set the breakpoints to next instruction of the instruction to change
to the STOP/HALT mode, the STOP/HALT mode is released by the break.
■About the frequency control register (FCON0,1) in case of nanoEASE use
- Do not write the program made into the clock mode which is not mounted for the OSCM0/OSCM1 bit
of FCON0 in the flash memory of target LSI. When this program is written in and the emulation is
executed, the operation about execution becomes impossible, because the clock is not supplied to
CPU. And DTU8+nanoEASE cannot be started by target LSI which wrote in this program. In these
cases, Error number: 6300H is displayed.
- The OSCM0/OSCM1 bit of FCON0 cannot be changed in the SFR window on DTU8.
- When ENOSC and SYSCLK of FCON1 are set to 1, even if ENOSC is set to 0 in the SFR window on
DTU8, the display of SYSCLK is still 1. However, SYSCLK inside target LSI is 0. Therefore, the
emulation is executed in the state of SYSCLK=0 as it was operated in the SFR window.
