Remark
Condition for clearing (STDn 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
• After reset
Condition for clearing (SPDn bit = 0)
• At the rising edge of the address transfer byte’s first
• When the IICEn bit changes from 1 to 0 (operation
