Description
Bus Busy
This bit enables to confirm whether the I
occupied or released and to issue start/stop conditions
in master mode. With the clock synchronous serial
format, this bit has no meaning. With the I
this bit is set to 1 when the SDA level changes from
high to low under the condition of SCL = high, assuming
that the start condition has been issued. This bit is
cleared to 0 when the SDA level changes from low to
high under the condition of SCL = high, assuming that
the stop condition has been issued. Write 1 to BBSY
and 0 to SCP to issue a start condition. Follow this
procedure when also re-transmitting a start condition.
Write 0 in BBSY and 0 in SCP to issue a stop condition.
To issue start/stop conditions, use the MOV instruction.
Start/Stop Issue Condition Disable
The SCP bit controls the issue of start/stop conditions in
master mode.
To issue a start condition, write 1 in BBSY and 0 in
SCP. A repeated start condition is issued in the same
way. To issue a stop condition, write 0 in BBSY and 0 in
SCP. This bit is always read as 1. If 1 is written, the
data is not stored.
SDA Output Value Control
This bit is used with SDAOP when modifying output
level of SDA. This bit should not be manipulated during
transfer.
0: When reading, SDA pin outputs low.
1: When reading, SDA pin outputs high.
When writing, SDA pin is changed to output low.
When writing, SDA pin is changed to output Hi-Z
(outputs high by external pull-up resistance).
