27.5.5 I
In master-receive mode, reading the I2DR allows a read to occur and initiates next the byte data
to be received. In slave mode, the same function is available once the I

R
Slave read/write. When IAAS is set, SRW indicates the value of the R/W command bit of
the calling address sent from the master. SRW is valid only when a complete transfer has
occurred, no other transfers have been initiated, and the I
address match.
0 Slave receive, master writing to slave.
1 Slave transmit, master reading from slave.

1 An interrupt is pending, which causes a processor interrupt request (if IIEN = 1). Set
Received acknowledge. The value of I2C_SDA during the acknowledge bit of a bus cycle.

• Complete one byte transfer (set at the falling edge of the ninth clock)
• Reception of a calling address that matches its own specific address in slave-receive
• Arbitration lost
C interrupt. Must be cleared by software by writing a zero in the interrupt routine.
