• The RESER_N pin has an internal pull-up resistor
• The low-speeed oscillation stop deteciton time is typ. 3 ms (Not available on ML610Q415)
• 250 ms, 1 sec, 4 sec, or 16 sec can be selected as the watchdog timer (WDT) overflow period
• Built-in reset status register (RSTAT) indicating the reset generation causes
• Only the CPU is reset by the BRK instruction (neither the RAM area nor the SFR area are reset).

This LSI has the five reset functions shown below. If any of the five reset conditions is satisfied, this LSI enters system
reset mode.
• Reset by the RESET_N pin
• Reset by power-on detection
• Reset by the low-speed oscillation stop detection (Not available on ML610Q415)
• Reset by the 2
• Software reset by execution of the BRK instruction
Figure 3-1 shows the configuration of the reset generation circuit.
