IIC Data I/O Register (IICD)
Transfer Complete Flag. This bit is set on the completion of a byte transfer. This bit is only valid during or
immediately following a transfer to the IIC module or from the IIC module.The TCF bit is cleared by reading the
IICD register in receive mode or writing to the IICD in transmit mode.
0 Transfer in progress
1 Transfer complete
Addressed as a Slave. The IAAS bit is set when the calling address matches the programmed slave address or
when the GCAEN bit is set and a general call is received. Writing the IICC register clears this bit.
0 Not addressed
1 Addressed as a slave
Bus Busy. The BUSY bit indicates the status of the bus regardless of slave or master mode. The BUSY bit is set
when a start signal is detected and cleared when a stop signal is detected.
0 Bus is idle
1 Bus is busy
Arbitration Lost. This bit is set by hardware when the arbitration procedure is lost. The ARBL bit must be cleared
by software by writing a 1 to it.
0 Standard bus operation
1 Loss of arbitration
Slave Read/Write. When addressed as a slave, the SRW bit indicates the value of the R/W command bit of the
calling address sent to the master.
0 Slave receive, master writing to slave
1 Slave transmit, master reading from slave
IIC Interrupt Flag. The IICIF bit is set when an interrupt is pending. This bit must be cleared by software, by
writing a 1 to it in the interrupt routine. One of the following events can set the IICIF bit:
0 No interrupt pending
1 Interrupt pending
Receive Acknowledge. When the RXAK bit is low, it indicates an acknowledge signal has been received after
the completion of one byte of data transmission on the bus. If the RXAK bit is high it means that no acknowledge
signal is detected.
0 Acknowledge received
1 No acknowledge received
