Description
Bus Busy
This bit enables to confirm whether the I
occupied or released and to issue start and stop
conditions in master mode. 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 to BBSY and 0 to SCP to
issue a stop condition. To issue a start/stop
condition, use the MOV instruction.
Start Condition/Stop Condition Prohibit
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.
Monitors the output level of SDA.
0: When reading, SDA pin outputs low.
1: When reading, SDA pin outputs high.
The write value must always be 1.
Reserved
The write value must always be 1.
This bit monitors SCL output level. When reading
and SCLO is 1, SCL pin outputs high. When
reading and SCLO is 0, SCL pin outputs low.
Reserved
This bit is always read as 1.
