When the transfer end interrupt is selected, the interrupt is generated when all stop bits have been completely
transferred.
Set 1 bit (SLCmn1, SLCmn0 = 0, 1) during UART reception.
Set no stop bit (SLCmn1, SLCmn0 = 0, 0) in the CSI mode.
Set 1 bit (SLCmn1, SLCmn0 = 0, 1) or 2 bits (SLCmn1, SLCmn0 = 1, 0) during UART transmission.

Notes 1. The SCR00 register only.
2. 0 is always added regardless of the data contents.
Caution Be sure to clear bits 3, 6, and 11 to "0" (Also clear bit 5 of the SCR01 register to 0). Be sure to set bit
2 to "1".
Remark m: Unit number (m = 0), n: Channel number (n = 0, 1), p: CSI number (p = 00)

Outputs odd parity.
Selection of data transfer sequence in CSI and UART modes
No stop bit
Stop bit length = 1 bit
Stop bit length = 2 bits (mn = 00 only)
Setting prohibited
Setting of data length in CSI and UART modes
9-bit data length (stored in bits 0 to 8 of the SDRmn register) (settable in UART mode only)
