WREL0
Be sure to set this bit (1) while the SCL0 and SDA0 lines are at high level.
Condition for clearing (IICE0 = 0)
• Cleared by instruction
• Reset
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
• Reset
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

Enable operation.
Normal operation
This exits from the current communications and sets standby mode. This setting is automatically cleared
to 0 after being executed.
Its uses include cases in which a locally irrelevant extension code has been received.
The SCL0 and SDA0 lines are set to high impedance.
The following flags of IIC control register 0 (IICC0) and IIC status register 0 (IICS0) are cleared to 0.
• STT0 • SPT0 • MSTS0 • EXC0 • COI0 • TRC0 • ACKD0 • STD0
Do not cancel wait
Cancel wait. This setting is automatically cleared after wait is canceled.
