How to use UART /CTS to wake up a chip? Issue Date：2015-02-11
Please set the WKCTSIEN (UART_INTEN[9]) and MODEMIEN (UART_INTEN[3]) after initiating UART and /CTS function. When the /CTS input pin changes the state from high to low or from low to high, it will generate the modem interrupt to wake up a chip.
