Warm reset by RESET_N pinWhen resetting with the RESET_N pin, set the RESET_N pin to "Low" for at least 17.2 μs or more while thepower supply voltage is within the operating range.When the "Low" period of a RESET_N pin is longer than "Internal processing time", after a RESET_N pinchanges to "High", Internal reset is released after "CPU waiting time" elapsed.When the "Low" period of a RESET_N pin is shorter than "Internal processing time", after internal reset isextended and from a RESET_N pin changes "Low", Internal reset is release after "Internal processing time" +"CPU waiting time" has elapsed, internal reset will be released.DVDD5 = DVDD5A = DVDD5B = AVDD5DVDD5Operation Voltage rangeRESET_N pinInternal resetInternal processing time(tIRST)CPU OperationstartCPU waiting time(tCPUWT)RESET_N pinInternal resetCPU waiting time(tCPUWT)CPU Operation startWhen RESET_N pin reset time is longer than internal processing time (tIRST)When RESET_N pin reset time is less than internal processing time (tIRST)Internal processing time(tIRST)Figure 3.5 Warm reset action3.2.2.2.
