10: Master receive mode
11: Master transmit mode
Both these bits will be cleared by hardware when they
lose in a bus contention in master mode with the I
format. In slave receive mode with I
R/W bit in the first frame immediately after the start
condition sets these bits in receive mode or transmit mode
automatically by hardware.
Modification of the TRS bit during transfer is deferred until
transfer is completed, and the changeover is made after
completion of the transfer.
