3.2.2.1. Warm reset by RESET_N pin

When resetting with the RESET_N pin, set the RESET_N pin to "Low" for at least 17.2 μs or more while the
power 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 pin
changes 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 is
extended 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.

3.2.2.2. Warm reset by internal reset

In case of reset asserted by internal factors, such as SIWDT, OFD, LVD, LOCKUP, and <SYSRESETREQ>,
Internal reset is released after "Internal processing time" + "CPU waiting time" elapsed.
