(6) Operation when arbitration loss occurs (no communication after arbitration loss)
(a) When arbitration loss occurs during transmission of slave address data
ST AD6 to AD0
L1: IICS = 01000110B (Example: When ALD is read during interrupt servicing)
∆ 2: IICS = 00000001B
Remark L: Always generated
∆: Generated only when SPIE = 1
(b) When arbitration loss occurs during transmission of extension code
ST AD6 to AD0
L1: IICSn = 0110X010B (Example: When ALD is read during interrupt servicing)
IICC's LREL is set to 1 via software
∆ 2: IICS = 00000001B
Remark L: Always generated
∆: Generated only when SPIE = 1
