TCA9548A: Cannot write to the device

Genius 9880 points
Part Number: TCA9548A

Hi Team,

Good day.

Customer is having issue when addressing  TCA9548A from an 8 bit PIC microcontroller. Please see inquiry below.

"
 I am using an 8-bit Microcomputer PIC and I'm programming using the MPLAB environment.  The I2C library is called I2CSIMPLE.

Problem:
The standard write to slave function expects to see a slave address, a register address and the data byte to be transmitted. The TCA9548A has no register address because it has only one register. So I cannot write to the device!

Regards,
