16.5 I2C Bus Control
T
5CL8
Note 1: I2CAR is write-only register, which cannot be used with any of read-modify-write instruction such as bit manipulation, etc.
Note 2: Do not set I2CAR to "00H" to avoid the incorrect response of acknowledgment in slave mode. ( If "00H" is set to I2CAR as
the Slave Address and a START Byte "01H" in I
2
C bus standard is recived, the device detects slave address match.)
Note 1: Switch a mode to port after confirming that the bus is free.
Note 2: Switch a mode to I
2
C bus mode after confiming that the port is high level.
Note 3: SBICRB has write-only register and must not be used with any of read-modify-write instructions such as bit manipulation,
etc.
Note 4: When the SWRST (Bit1, 0 in SBICRB) is written to "10", "01" in I
2
C bus mode, software reset is occurred. In this case, the
SBICRA, I2CAR, SBISRA and SBISRB registers are initialized and the bits of SBICRB except the SBIM (Bit3, 2 in SBI-
CRB) are also initialized.
