External interrupt 0-3 input source
INT40 - INT47
I
External interrupt 40-47 input source
RST
————
I
The device will be reset by a low voltage on this pin longer than 10us, an internal
resistor about 30
kΩ to VDD, So using only an external capacitor to GND can cause a
power-on reset.

I/O
Single simulation interface. If the power on or down slope of VDD is greater than
500ms/V, it is recommended to connect 47k-1m resistor to GND or VDD to increase
the stability of the chip
Note: When P1.0-1.3 used as debug interface, functions of P1.0-1.3 are blocked.
