(*1) This pin can only be used as ADC input, cannot use it as normal I/O. when not using, just connect nothing. When used as ADC input, the input voltage range is 0~1.0V.
(*2) UART0 is serial port, during power on progress; this serial port will output something, which can be ignored. 2.3Test PinDefinition Table 2 shows the generaltest pindefinition of TYWE3L PIN NO. NAME TEST
