Transmit/receive operation starts by writing data to the G0TB register.
Read the G0RB register after the receive operation is completed.
k = 0,1
NOTE:
1. Set all the interrupt request flags to 0. If any of these flags remains 1, the IR bit in the IIOkIC register does not become 1 when an
interrupt request is generated in the same register (Interrupt does not occur).
