Section 16 I
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 by setting of bit CLR3 to CLR0 or by clearing ICE
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 by setting of bit CLR3 to CLR0 or by clearing
4. Initialize (re-set) the IIC registers.

bit.
bit to 0, and wait for two transfer rate clock cycles.
ICE bit.
In master mode, if an instruction to generate a start condition is immediately followed by an
instruction to generate a stop condition, neither condition will be output correctly. To output
consecutive start and stop conditions, after issuing the instruction that generates the start
condition, read the relevant ports, check that SCL and SDA are both low, then issue the
instruction that generates the stop condition. Note that SCL may not yet have gone low when
BBSY is cleared to 0.
Either of the following two conditions will start the next transfer. Pay attention to these
conditions when reading or writing to ICDR.
Table 16.6 shows the timing of SCL and SDA output in synchronization with the internal
clock. Timings on the bus are determined by the rise and fall times of signals affected by the
bus load capacitance, series resistance, and parallel resistance.
Write access to ICDR when ICE = 1 and TRS = 1 (including automatic transfer from
ICDRT to ICDRS)
Read access to ICDR when ICE = 1 and TRS = 0 (including automatic transfer from
ICDRS to ICDRR)
