CHAPTER 17 ASYNCHRONOUS SERIAL INTERFACE C (UARTC)
(5) UARTCn option control register 1 (UCnOPT1)
The UCnOPT1 register is an 8-bit register that controls the serial transfer operation of UARTCn.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.
Caution Set the UCnEBE bit while the operation of UARTC is disabled (UCnCTL0.UCnPWR = 0).
After reset: 00H

Extension bit enable/disable
0 Extension-bit operation is prohibited. Transmission/reception is performed
in the data length set by the UCnCTL0.UCnCL bit.
1 Extension-bit operation enabled. Transmission/reception can be
performed in 9-bit character length.
• When setting the UCnEBE bit to 1, and transmitting in 9-bit data length, be sure to
set the following. If this setting is not performed, the setting of UCnEBE bit is invalid.
• UCnCTL0.UCnPS1, UCnPS0 = 00 (no parity)
• CnCTL0.UCnCL = 1 (8-bit character length)
• If transmitting or receiving in the LIN communication format, set the UCnEBE to 0.
Remark n = 0 to 5 (V850ES/JH3-E)
n = 0 to 7 (V850ES/JJ3-E)
The following shows the relationship between the register setting value and the data format.
