SPB2IO=0, RXDMON=0, SPB2DT=0
Serial Port Register
| RXDMON | Serial input data monitor bit (The state of the RXD terminal is shown.) 0 (0): RXD pin is low. 1 (1): RXD pin is high. |
| SPB2DT | Serial port break data select bit (The output level of TxD terminal is selected when SCR.TE = 0.) 0 (0): Low level is output on TXD pin 1 (1): High level is output on TXD pin |
| SPB2IO | Serial port break I/O bit (It’s selected whether the value of SPB2DT is output to TxD terminal.) 0 (0): The value of SPB2DT bit is not output in TXD pin. 1 (1): The value of SPB2DT bit is output in TXD pin. |
| Reserved | These bits are read as 00000. The write value should be 00000. |
