(3) IIC status register 0 (IICS0)
Address: FFF56H
Symbol
This register indicates the status of I
IICS0 is read by a 1-bit or 8-bit memory manipulation instruction only when STT0 = 1 and during the wait
period.
Reset signal generation clears this register to 00H.
IICS0
Note This register is also cleared when a 1-bit memory manipulation instruction is executed for bits
Remark
Condition for clearing (MSTS0 = 0)
• When a stop condition is detected
• When ALD0 = 1 (arbitration loss)
• Cleared by LREL0 = 1 (exit from communications)
• When IICE0 changes from 1 to 0 (operation stop)
• Reset
Condition for clearing (ALD0 = 0)
• Automatically cleared after IICS0 is read
• When IICE0 changes from 1 to 0 (operation stop)
• Reset
Condition for clearing (EXC0 = 0)
• When a start condition is detected
• When a stop condition is detected
• Cleared by LREL0 = 1 (exit from communications)
• When IICE0 changes from 1 to 0 (operation stop)
• Reset

other than IICS0. Therefore, when using the ALD0 bit, read the data of this bit before the data
of the other bits.

Extension code was not received.
Extension code was received.
Slave device status or communication standby status
Master device communication status
This status means either that there was no arbitration or that the arbitration result was a “win”.
This status indicates the arbitration result was a “loss”. MSTS0 is cleared.

Condition for setting (MSTS0 = 1)
• When a start condition is generated
Condition for setting (ALD0 = 1)
• When the arbitration result is a “loss”.
Condition for setting (EXC0 = 1)
• When the higher four bits of the received address
data is either “0000” or “1111” (set at the rising edge
of the eighth clock).
