(4) Operation without communication
(a) Start ~ Code ~ Data ~ Data ~ Stop
1: IICS0 = 00000001B
Remark : Generated only when SPIE0 = 1
(5) Arbitration loss operation (operation as slave after arbitration loss)
When the device is used as a master in a multi-master system, read the MSTS0 bit each time interrupt request signal
INTIICA0 has occurred to check the arbitration result.
(a) When arbitration loss occurs during transmission of slave address data
(i) When WTIM0 = 0
1: IICS0 = 0101×110B
2: IICS0 = 0001×000B
3: IICS0 = 0001×000B
4: IICS0 = 00000001B
Remark : Always generated
: Generated only when SPIE0 = 1
