Set these bits to ‘100
Set transmission data
Reception data can be read
Set a transfer rate
Set these bits to ‘101
Set these bits to ‘110
Select the internal clock or external clock
Select the stop bit
Select whether parity is included and whether odd or even
Select the TxD/RxD input/output polarity
Select the count source for the UiBRG register
Select CTS or RTS to use
Transmit register empty flag
Enable or disable the CTS or RTS function

LSB first or MSB first can be selected when transfer data is 8 bits long. Set this
bit to “0” when transfer data is 7 or 9 bits long.
Set this bit to “1” to enable transmission
Transmit buffer empty flag
Set this bit to “1” to enable reception
Reception complete flag
Select the source of UART2 transmit interrupt
Set to “0”
Set this bit to “1” to use UART2 inverted data logic
Set to “0”
