Reception Disable
This bit enables or disables the next operation when TRS is 0
and ICDRR is read.
0: Enables next reception
1: Disables next reception
Master/Slave Select
Transmit/Receive Select
When arbitration is lost in master mode, MST and TRS are both
reset by hardware, causing a transition to slave receive mode.
Modification of the TRS bit should be made between transfer
frames.
Operating modes are described below according to MST and
TRS combination.
00: Slave receive mode
01: Slave transmit mode
10: Master receive mode
11: Master transmit mode
Transfer Clock Select 3 to 0
These bits are valid only in master mode. Make setting
according to the required transfer rate. For details on the
transfer rate, see table 17.2.
