Bit
Set by Hardware When:
Cleared by Hardware When:
MASTER
A START is generated.
A STOP is generated.
Arbitration is lost.
TXMODE
START is generated.
The SMBus interface enters transmitter mode
(after SMB0DAT is written before the start of
an SMBus frame).
A START is detected.
Arbitration is lost.
SMB0DAT is not written before the
start of an SMBus frame.
STA
A START followed by an address byte is
received.
Must be cleared by software.
STO
A STOP is detected while addressed as a
slave.
Arbitration is lost due to a detected STOP.
A pending STOP is generated.
ACKRQ
A byte has been received and an ACK
response value is needed.
After each ACK cycle.
ARBLOST
A repeated START is detected as a MASTER
when STA is low (unwanted repeated START).
SCL is sensed low while attempting to gener-
ate a STOP or repeated START condition.
SDA is sensed low while transmitting a ‘1’
(excluding ACK bits).
Each time SI is cleared.
ACK
The incoming ACK value is low (ACKNOWL-
EDGE).
The incoming ACK value is high (NOT
ACKNOWLEDGE).
SI
A START has been generated.
Lost arbitration.
A byte has been transmitted and an
ACK/NACK received.
A byte has been received.
A START or repeated START followed by a
slave address + R/W has been received.
A STOP has been received.
Must be cleared by software.
