NOTES:
1. The bits used for transmit/receive data are as follows:
• Bit 0 to bit 6 when transfer data is 7-bit long
• Bit 0 to bit 7 when transfer data is 8-bit long
• Bit 0 to bit 8 when transfer data is 9-bit long.
2. Set bit 4 to bit 5 in the U0C1 and U1C1 registers to "0". The U0IRS, U1IRS, U0RRM and U1RRM bits are included
in the UCON register.

Set transmission data
Reception data can be read
Set a transfer rate
Set these bits to "100b" when transfer data is 7-bit long
Set these bits to "101b" when transfer data is 8-bit long
Set these bits to "110b" when transfer data is 9-bit long
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
Select TXDi pin output mode
Set to "0"
LSB first or MSB first can be selected when transfer data is 8-bit long. Set this
bit to "0" when transfer data is 7- or 9-bit 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 inverted data logic
Set to "0"
Set to "0"
Set to "0"
Set to "0"
Set to "0"
Select the source of UART0/UART1 transmit interrupt
Set to "0"
Invalid because the CLKMD1 bit = 0
Set to "0"
Set this bit to "1" to accept as input the UART0 CTS0 signal from the P6_4 pin
Set to "0"
