Description
7
SUnINTS
This bit is used to choose the operation mode of the transmission/reception interrupt.
Refer to the description about SUnRIMD bit and SUnTIMD bit.
6
SUnTIMD
This bit is used to choose the timing of transmission interrupt occurrence.
When the SUnINTS bit is “0”:
0: The interrupt occurs at the end of data transmission (Initial)
1: The Interrupt occurs at the start and end of data transmission
When the SUnINTS bit is “1”:
0: The interrupt occurs at the end of data transmission
1: The Interrupt occurs at the start of data transmission
5
SUnRIMD
This bit is used to choose the timing of reception interrupt occurrence.
When the SUnINTS bit is “0”:
0: The interrupt occurs at the end of data reception (Initial)
1: The Interrupt occurs at the start and end of data reception
When the SUnINTS bit is “1”:
0: The interrupt occurs at the end of data reception
1: The Interrupt occurs at the start of data reception
4 to 2

Reserved bit
1,0
SUnMD1 to
SUnMD0
This bit is used to choose the communication mode of the serial communication unit.
00: SSIO mode (Initial value)
01: SSIO mode
10: UART Full-duplex communication mode
11: UART Half-duplex communication mode x 2ch
[Note]
Ÿ
Be sure to set the SUnMOD register while communication is stopped (SUnCON register = 0x00) and do
not rewrite it during communication. If it is rewritten during communication, data may be transmitted or
received incorrectly.
