Reception Disable
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 and should be set
according to the necessary transfer rate. For details on
transfer rate, see table 17.2.
