In the following text, it is assumed that ENS1 = 1.
STA
,
THE
START F
LAG
STA = 1: When the STA bit is set to enter a master mode, the I
2
C
hardware checks the status of the I
2
C-bus and generates a START
condition if the bus is free. If the bus is not free, then I
2
C waits for a
STOP condition (which will free the bus) and generates a START
condition after a delay of a half clock period of the internal serial
clock generator.
If STA is set while I
2
C is already in a master mode and one or more
bytes are transmitted or received, I
2
C transmits a repeated START
condition. STA may be set at any time. STA may also be set when
I
2
C is an addressed slave.
STA = 0: When the STA bit is reset, no START condition or repeated
START condition will be generated.
STO
,
THE
STOP F
LAG
STO = 1: When the STO bit is set while I
2
C is in a master mode, a
STOP condition is transmitted to the I
2
C-bus. When the STOP
condition is detected on the bus, the I
2
C hardware clears the STO
flag. In a slave mode, the STO flag may be set to recover from an
error condition. In this case, no STOP condition is transmitted to the
I
2
C-bus. However, the I
2
C hardware behaves as if a STOP condition
has been received and switches to the defined “not addressed”
slave receiver mode. The STO flag is automatically cleared by
hardware.
