The following shows an example of the processing of the slave device by an INTIIC0 interrupt (it is assumed that 

no extension codes are used here).  During an INTIIC0 interrupt, the status is confirmed and the following steps are 

executed. 

 

<1>  When a stop condition is detected, communication is terminated. 

<2>  When a start condition is detected, the address is confirmed.  If the address does not match, communication 

is terminated.  If the address matches, the communication mode is set and wait is released, and operation 

returns from the interrupt (the ready flag is cleared). 

<3>  For data transmission/reception, when the ready flag is set, operation returns from the interrupt while the I

2

C0 

bus remains in the wait status. 

 

Remark

  <1> to <3> in the above correspond to <1> to <3> in
