20.10.1 Writing to the S00 Register
When the start condition is not generated, the SCL pin may output the short low-signal ("L") by setting the
S00 register. Set the register when the SCL pin outputs an "L" signal.
20.10.2 AL Flag
When the arbitration lost is generated and the AL flag in the S10 register is set to "1" (detected), the AL
flag can be cleared to "0" (not detected) by writing a transmit data to the S00 register. The AL flag should
be cleared at the timing when master geneates the start condition to start a new transfer.
