10.3.5 I C interrupt requests (INTIICn)
The following shows the value of IIC status register n (IICSn) at the INTIICn interrupt request generation timing and
at the INTIICn interrupt timing (n = 0, 1).
(1) Master device operation
(a) Start ~ Address ~ Data ~ Data ~ Stop (normal transmission/reception)
<1> When WTIMn = 0
ST AD6 to AD0
L1: IICSn = 10XXX110B
L2: IICSn = 10XXX000B
L3: IICSn = 10XXX000B (WTIMn = 0)
L4: IICSn = 10XXXX00B
∆ 5: IICSn = 00000001B
Remark
<2> When WTIMn = 1
ST AD6 to AD0
L1: IICSn = 10XXX110B
