Bits 9:8 SADD[9:8]: Slave address bit 9:8 (master mode)
In 7-bit addressing mode (ADD10 = 0):
These bits are don’t care
In 10-bit addressing mode (ADD10 = 1):
These bits should be written with bits 9:8 of the slave address to be sent
Note: Changing these bits when the START bit is set is not allowed.
Bits 7:1 SADD[7:1]: Slave address bit 7:1 (master mode)
In 7-bit addressing mode (ADD10 = 0):
These bits should be written with the 7-bit slave address to be sent
In 10-bit addressing mode (ADD10 = 1):
These bits should be written with bits 7:1 of the slave address to be sent.
Note: Changing these bits when the START bit is set is not allowed.
Bit 0 SADD0: Slave address bit 0 (master mode)
In 7-bit addressing mode (ADD10 = 0):
This bit is don’t care
In 10-bit addressing mode (ADD10 = 1):
This bit should be written with bit 0 of the slave address to be sent
Note: Changing these bits when the START bit is set is not allowed.
