Module reset pin, low level reset, low level duration is greater
I
than or equal to 2ms.
Burn emulation mode selection. The SOP2 pin has a built-in 2.4K
I
pull-down resistor; when using it, an external pull-up resistor
100R is required to pull the pin level high. Normal work is low.
Burn emulation mode selection. The SOP1 pin has a built-in
I
100K pull-down resistor; when using, an external pull-up resistor
10K is required to pull the pin level high. Normal work is high.
Burn emulation mode selection. The SOP0 pin has a built-in
100K pull-down resistor; when using it, an external pull-up

resistor of 10K is required to pull the pin level high. Normal work
is low.
Equipment power supply VDC: 2.4V~3.6V (above 300mA)
