The XC864 has five types of reset: power-on reset, hardware reset, watchdog timer
reset, power-down wake-up reset, and brownout reset.
When the XC864 is first powered up, the status of certain pins (see
defined to ensure proper start operation of the device. At the end of a reset sequence,
the sampled values are latched to select the desired boot option, which cannot be
modified until the next power-on reset or hardware reset. This guarantees stable
conditions during the normal operation of the device.
In order to power up the system properly, the external reset pin RESET must be asserted
until V

A typical application example is shown in

Typically, the time taken for V
reaches 2.3V. Hence, based on the condition that 10% to 90% V
than 500 µs, the RESET pin should be held low for 500 µs typically. See
