(13) Precautions when using multi-master I
Select the no-division mode and set the main clock frequency to f(X
Specify byte (.B) as data size to access multi-master I
The precautions when the read-modify-write instruction such as BSET, BCLR etc. is executed for
each register of the multi-master I

When executing the read-modify-write instruction for this register during transfer, data may
become a value not intended.
When the read-modify-write instruction is executed for this register at detecting the STOP con-
dition, data may become a value not intended. It is because hardware changes the read/write
bit (RBW) at the above timing.
Do not execute the read-modify-write instruction for this register because all bits of this register
are changed by hardware.
When the read-modify-write instruction is executed for this register at detecting the START
condition or at completing the byte transfer, data may become a value not intended. Because
hardware changes the bit counter (BC0–BC2) at the above timing.
The read-modify-write instruction can be executed for this register.
Since the read value of high-order 4 bits is indeterminate, the read-modify-write instruction
cannot be used.
Since the value of all bits is indeterminate, the read-modify-write instruction cannot be used.
