C interrupt request (INTIIC)

The following shows the value of the IIC status register (IICS) at the INTIIC interrupt request generation timing and
at the INTIIC interrupt timing.
(1) Master device operation
(a) Start ~ Address ~ Data ~ Data ~ Stop (normal transmission/reception)
<1> When WTIM = 0
ST AD6 to AD0
L1: IICS = 10XXX110B
L2: IICS = 10XXX000B
L3: IICS = 10XXX000B (WTIM = 0)
L4: IICS = 10XXXX00B
∆ 5: IICS = 00000001B
Remark L: Always generated
∆: Generated only when SPIE = 1
X: Don't care
<2> When WTIM = 1
ST AD6 to AD0
L1: IICS = 10XXX110B
