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 I
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 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.
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).
