function
Item
• 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, parity bit and stop bit are not reversed.
•TxD, RxD I/O polarity switch
This function is reversing TxD port output and RxD port input. All I/O data level is reversed.
