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. 12 Revision History Revision No. Date Description 1.0 Dec. 21, 2011 First edition. 2.0 Jan. 17, 2012 Clerical error correction
