Setting of parity bit in UART mode
Transmission Reception
0
0
Does not output the parity bit.
Receives without parity
0
1
Outputs 0 parity

.
No parity judgment
1
0
Outputs even parity.
Judged as even parity.
1
1
Outputs odd parity.
Judges as odd parity.
Be sure to set PTCmn1, PTCmn0 = 0, 0 in the CSI mode.

Setting
prohibited
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.

Setting of data length in CSI and UART modes
0
1
9-bit data length (stored in bits 0 to 8 of the SDRmn register) (settable in UART mode only)
1
0
7-bit data length (stored in bits 0 to 6 of the SDRmn register)
1
1
8-bit data length (stored in bits 0 to 7 of the SDRmn register)
Other than above Setting prohibited
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)
