Select function
• 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 (UART2)
This function is reversing TXD port output and RXD port input. All I/O data
level is reversed.
