19.7.6 Operation when arbitration loss occurs (no communication after arbitration loss)
(1) When arbitration loss occurs during transmission of slave address data
ST AD6 to AD0 R/W ACK D7 to D0 ACK D7 to D0 ACK SP
S1 Δ2
S1: IICSn register = 01000110B (Example: When IICSn.ALDn bit is read during interrupt servicing)
Δ 2: IICSn register = 00000001B
Remarks 1. S: Always generated
Δ: Generated only when IICCn.SPIEn bit = 1
2. n = 0 to 2
(2) When arbitration loss occurs during transmission of extension code
ST AD6 to AD0 R/W ACK D7 to D0 ACK D7 to D0 ACK SP
S1 Δ2
S1: IICSn register = 0110X010B (Example: When ALDn bit is read during interrupt servicing)
IICCn.LRELn bit is set to 1 by software
Δ 2: IICSn register = 00000001B
Remarks 1. S: Always generated
Δ: Generated only when SPIEn bit = 1
X: don’t care
2. n = 0 to 2
