Preliminary document
Specifications in this document are tentative and subject to change.
Registers and Settings Used in Clock Asynchronous Serial I/O Mode
Bit
Set the transmit data.
The receive data can be read.
Overrun error flag
Framing error flag
Parity error flag
Error sum flag
Set the bit rate.
Set to 101b when transfer data is 8 bits long.
Set to 110b when transfer data is 9 bits long.
Select an internal or external clock.
Select one or two stop bits.
Select whether parity is enabled and whether odd or even.
Transmit register empty flag
Select the output type (CMOS or N-channel open-drain output) of the TXD pin.
Set to 0 (transmit data is output at the falling edge and receive data is input at the rising
edge of the transfer clock).
Select LSB first or MSB first when transfer data is 8 bits long.
Set to 0 (LSB first) when transfer data is 7 bits or 9 bits long.
Set to 1 to enable transmission.
Transmit buffer empty flag
Set to 1 to enable reception.
Reception complete flag
Select the UART0 transmit interrupt source to be transmit buffer empty or transmission
complete.
Set to 0 (continuous receive mode disabled).
