Description 
SPB2IO 
R/W 
Serial Port Break Input/Output 
Indicates input or output of the serial port TxD pin. 
When the TxD pin is actually used as a port outputting 
the SPB2DT bit value, the TE bit in SCSCR should be 
cleared to 0. 
0: SPB2DT bit value not output to TxD pin 
1: SPB2DT bit value output to TxD pin 
SPB2DT 
R/W 
Serial Port Break Data 
Indicates the input data of the RxD pin and the output 
data of the TxD pin used as serial ports. Input/output is 
specified by the SPB2IO bit. When the TxD pin is set to 
output, the SPB2DT bit value is output to the TxD pin. 
The RxD pin status is read from the SPB2DT bit 
regardless of the SPB2IO bit setting. However, RxD 
input and TxD output must be set in the PFC. 
0: Input/output data is low level 
1: Input/output data is high level
