The following items are not initialized:
• Actual register values (ICDR, SAR, SARX, ICMR, ICCR, ICSR, DDCSWR, and STCR)
• Internal latches used to retain register read information for setting/clearing flags in the ICMR,
• 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
• When initialization is performed by means of the DDCSWR register, the write data for bits
• 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 setting of bits CLR3 to CLR0, or
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 setting of bits CLR3 to CLR0, or
4. Initialize (re-set) the IIC registers.

taken as necessary.
CLR3 to CLR0 is not retained. To perform IIC clearance, bits CLR3 to CLR0 must be written
to simultaneously using an MOV instruction. Do not use a bit manipulation instruction such as
BCLR. Similarly, when clearing is required again, all the bits must be written to
simultaneously in accordance with the setting.

necessary to enable correct communication as a system.
