17.4 Registers
806
(1) UARTCn control register 0 (UCnCTL0)
The UCnCTL0 register is an 8-bit register that controls the UARTCn serial transfer operation.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 10H.
UCnCTL0
After reset: 10H

Remark
UCnPWR
UCnPWR
UCnRXE
The UARTCn operation is controlled by the UCnPWR bit. The TXDCn pin output
is fixed to high level by clearing the UCnPWR bit to 0 (fixed to low level if
UCnOPT0.UCnTDL bit = 1).
UCnTXE
• To start transmission, set the UCnPWR bit to 1 and then set the UCnTXE bit to 1.
• To initialize the transmission unit, clear the UCnTXE bit to 0, wait for two cycles of
• To start reception, set the UCnPWR bit to 1 and then set the UCnRXE bit to 1.
• To initialize the reception unit, clear the UCnRXE bit to 0, wait for two periods of
To stop transmission, clear the UCnTXE bit to 0 and then UCnPWR bit to 0.
