1: The transfer in CMDR should commence with a START or REPEATED START condition. If the bus is free when the command
is executed, a START condition is used. If the bus is busy, a REPEATED START is used.
• REPSAME: Transfer is to Same Address as Previous Address
Only used in 10-bit addressing mode, always write to 0 in 7-bit addressing mode.
Write this bit to one if the command in CMDR performs a repeated start to the same slave address as addressed in the previous
transfer in order to enter master receiver mode.
Write this bit to zero otherwise.
• TENBIT: Ten Bit Addressing Mode
0: Use 7-bit addressing mode.
1: Use 10-bit addressing mode. Must not be used when the TWIM is in SMBus mode.
• SADR: Slave Address
Address of the slave involved in the transfer. Bits 9-7 are don’t care if 7-bit addressing is used.
• READ: Transfer Direction
0: Allow the master to transmit data.
1: Allow the master to receive data.
