Condition for clearing (IICE0 = 0)
• Cleared by instruction
• When RESET is input
The standby mode following exit from communications remains in effect until the following communications entry
conditions are met.
• After a stop condition is detected, restart is in master mode.
• An address match or extension code reception occurs after the start condition.
Condition for clearing (LREL0 = 0)
• Automatically cleared after execution
• When RESET is input
When WREL0 is set (wait canceled) during the wait period at the ninth clock pulse in the transmission status
(TRC0 = 1), the SDA0 line goes into the high impedance state (TRC0 = 0).
Condition for clearing (WREL0 = 0)
• Automatically cleared after execution
• When RESET is input
Condition for clearing (SPIE0 = 0)
• Cleared by instruction

Stop operation. Reset IIC status register 0 (IICS0). Stop internal operation.
Enable operation.
Normal operation
This exits from the current communications operation and sets standby mode. This setting is
automatically cleared after being executed. Its uses include cases in which a locally irrelevant
extension code has been received.
The SCL0 and SDA0 lines go into the high impedance state.
The following flags of IIC status register 0 (IICS0) and IIC control register 0 (IICC0) are cleared.
• STD0 • ACKD0
Do not cancel wait.
