(8) UARTCn transmit data register L (UCnTXL), UARTCn transmit data register (UCnTX)
Cautions 1. In the transmission operation enable status (UCnPWR = 1 and UCnTXE = 1), Writing to the
The UCnTXL and UCnTX register is an 8-bit or 9-bit register used to set transmit data.
During LSB-first transmission when the data length has been specified as 7 bits, the transmit data is transferred to
bits 6 to 0 of the UCnRX register. During MSB-first transmission, the receive data is transferred to bits 7 to 1 of the
UCnRX register.
The access unit or reset value differs depending on the character length.
• Character length 7/8-bit (UCnOPT1.UCnEBE = 0)
• Character length 9-bit (UCnOPT1.UCnEBE = 0)
(b) Character length 9-bit (UCnOPT1.UCnEBE = 1)
(a) Character length 7/8-bit (UCnOPT1.UCnEBE = 0)
This register can be read or written in 8-bit units.
Reset sets this register to FFH.
This register can be read or written in 16-bit units.
Reset sets this register to 01FFH.
