Note The TRCn bit is cleared to 0 and SDA0n line becomes high impedance when the WRELn bit is set to
Remark
Condition for clearing (COIn bit = 0)
• When a start condition is detected
• When a stop condition is detected
• Cleared by LRELn bit = 1 (communication save)
• When the IICEn bit changes from 1 to 0 (operation
• After reset
Condition for clearing (TRCn bit = 0)
• When a stop condition is detected
• Cleared by LRELn bit = 1 (communication save)
• When the IICEn bit changes from 1 to 0 (operation
• Cleared by IICCn.WRELn bit = 1
• When the ALDn bit changes from 0 to 1 (arbitration
• After reset
Master
• When “1” is output to the first byte’s LSB (transfer
Slave
• When a start condition is detected
When not used for communication
Condition for clearing (ACKDn bit = 0)
• When a stop condition is detected
• At the rising edge of the next byte’s first clock
• Cleared by LRELn bit = 1 (communication save)
• When the IICEn bit changes from 1 to 0 (operation

Transmit status. The value in the SO latch is enabled for output to the SDA0n line (valid starting at
the falling edge of the first byte’s ninth clock).
