Pu ll -up Resistor
The external pull-up resistor is necessary. The digital output function of I/O only supports sink current capability, so the
open-drain output high is driven by pull-
up resistor, and output low is sunken by MCU’s pin.
Note: VCC shall be less than or equal to VDD of MCU1 and MCU2.
