Bit7:
BUSY: Busy Status Flag.
0: SMBus is free
1: SMBus is busy
Bit6:
ENSMB: SMBus Enable.
This bit enables/disables the SMBus serial interface.
0: SMBus disabled.
1: SMBus enabled.
Bit5:
STA: SMBus Start Flag.
0: No START condition is transmitted.
1: When operating as a master, a START condition is transmitted if the bus is free. (If the
bus is not free, the START is transmitted after a STOP is received.) If STA is set after one
or more bytes have been transmitted or received and before a STOP is received, a repeated
START condition is transmitted. STO should be explicitly cleared before setting STA to
logic 1.
Bit4:
STO: SMBus Stop Flag.
0: No STOP condition is transmitted.
1: Setting STO to logic 1 causes a STOP condition to be transmitted. When a STOP
condition is received, hardware clears STO to logic 0. If both STA and STO are set, a
STOP condition is transmitted followed by a START condition. In slave mode, setting the
STO flag causes SMBus to behave as if a STOP condition was received.
Bit3:
SI: SMBus Serial Interrupt Flag.
This bit is set by hardware when one of 27 possible SMBus states is entered. (Status code
0xF8 does not cause SI to be set.) When the SI interrupt is enabled, setting this bit causes
the CPU to vector to the SMBus interrupt service routine. This bit is not automatically
cleared by hardware and must be cleared by software.
Bit2:
AA: SMBus Assert Acknowledge Flag.
This bit defines the type of acknowledge returned during the acknowledge cycle on the
SCL line.
0: A “not acknowledge” (high level on SDA) is returned during the acknowledge cycle.
1: An “acknowledge” (low level on SDA) is returned during the acknowledge cycle.
Bit1:
FTE: SMBus Free Timer Enable Bit
0: No timeout when SCL is high
1: Timeout when SCL high time exceeds limit specified by the SMB0CR value.
Bit0:
TOE: SMBus Timeout Enable Bit
0: No timeout when SCL is low.
1: Timeout when SCL low time exceeds limit specified by Timer 3, if enabled.
