139 * In single master mode, data can be written by sending the register address
143 * If ten-bit I2C device addresses are used, the minimum chunk size must be six,
146 * Data in single master mode is transferred as follows:
153 * <S> <devR> --- <P>
155 * In multi-master mode, the data must immediately follow the address (an I2C
158 * 10-bit I2C device addresses are used).
160 * The 7-bit or 10-bit i2c address parameters is a runtime parameter.
