This bit enables to confirm whether the I
released and to issue start/stop conditions in master mode.
With the clocked synchronous serial format, this bit has no
meaning. With the I
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.
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
retransmit 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.
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.
This bit controls change of output level of the SDA pin by
modifying the SDAO bit. To change the output level, clear
SDAO and SDAOP to 0 or set SDAO to 1 and clear SDAOP
to 0 by the MOV instruction. This bit is always read as 1.
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).
