Multimaster Access of CLK104 on
TCA9548 Multiplexer
The TCA9548 multiplexer is shared between the I2C masters MSP430 and APU on the Gen 3
RFSoC. The operation to select the CLK104 device on the multiplexer and read/write operation
is completed in three steps in the I2C driver. When one master is accessing the device, the other
master should not access it.
