must be kept lower than 0.2 V before power-on.
Notes: The above ratings are values for causing a power-on reset.
When HST is set to “L”, apply power according to this table to cause a power-on reset irrespective of
whether or not a power-on reset is required.
For built-in resources in the device, re-apply power to the resources to cause a power-on reset.
