2.4 Reset Circuitry
It is recommended to use a 1.8V output MCU power supply monitor IC in order to
ensure a stable reset under power-on, power-down and under-voltage conditions.
2.5 Special Pins
IO_16 is used for boot mode selection. During power-on reset, pull high to boot
from FLASH and pull low to enter ISP mode. After reset, IO_0, IO_1, IO_2, and IO_3
are JTAG pins. IO_4 and IO_5 are ISP pins.
