C Bus Control Register 2 (ICCR2)
ICCR1 is an 8-bit readable/writable register that issues start/stop conditions, manipulates the SDA
pin, monitors the SCL pin, and controls reset in I
2
C control part.
Bit Bit Name Initial Value R/W Description
7 BBSY 0 R/W Bus Busy
This bit enables to confirm whether the I
2
C bus is occupied
or released and to issue start/stop conditions in master
mode. With the clocked synchronous serial format, this bit
has no meaning. With the I
2
C bus format, 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.
