Can SCI and IIC used simultaneously despite same address allocation?

Latest Updated:01/18/2008

Question:

The SCI register and IIC register have the same address allocation. Can SCI and IIC be used simultaneously?

Answer:

Simultaneous use of SCI and IIC is not possible for the H8S/2633 and H8S/2634 groups. Simultaneous use of SCI and IIC is possible for other products. When using, please set the SCI SMR, BRR, SCMR registers first, then switch to the IIC ICCR, ICSR, ICDR/SARX registers.
