• The value of the ICMR register bit counter (BC2 to BC0)
• Generated interrupt sources (interrupt sources transferred to the interrupt controller)
Notes on Initialization:
• Interrupt flags and interrupt sources are not cleared, and so flag clearing measures must be
• Basically, other register flags are not cleared either, and so flag clearing measures must be
• If a flag clearing setting is made during transmission/reception, the IIC module will stop
The value of the BBSY bit cannot be modified directly by this module clear function, but since the
stop condition pin waveform is generated according to the state and release timing of the SCL and
SDA pins, the BBSY bit may be cleared as a result. Similarly, state switching of other bits and
flags may also have an effect.
To prevent problems caused by these factors, the following procedure should be used when
initializing the IIC state.
1. Execute initialization of the internal state according to the ICE bit clearing.
2. Execute a stop condition issuance instruction (write 0 to BBSY and SCP) to clear the BBSY
3. Re-execute initialization of the internal state according to the ICE bit clearing.
4. Initialize (re-set) the IIC registers.

transmitting/receiving at that point and the SCL and SDA pins will be released. When
transmission/reception is started again, register initialization, etc., must be carried out as
necessary to enable correct communication as a system.
