(c) Start ~ Code ~ Data ~ Data ~ Stop (extension code transmission)
(i) When WTIMn = 0
1: IICSn = 1010×110B
2: IICSn = 1010×000B
3: IICSn = 1010×000B (Sets the WTIMn bit to 1)
4: IICSn = 1010××00B (Sets the SPTn bit to 1)
5: IICSn = 00000001B
Note To generate a stop condition, set the WTIMn bit to 1 and change the timing for generating the INTIICAn
interrupt request signal.
