_______
_______
Each of UART0 CTS and RTS pins can be assigned to separate pins
• Sleep mode selection (UART0, UART1)
This mode is used to transfer data to and from one of multiple slave micro-
computers
• Serial data logic switch (UART2)
This function is reversing logic value of transferring data. Start bit,and stop
bit are not reversed.
