(CBnCTL2.CBnCL3 to CBnCTL2.CBnCL0 bits = 0, 0, 0, 0)
(1) Clear the CBnCTL0.CBnPWR bit to 0.
(2) Set the CBnCTL1 and CBnCTL2 registers to specify the transfer mode.
(3) Set the CBnTXE, CBnRXE, and CBnSCE bits of the CBnCTL0 register to
(4) Set the CBnPWR bit to 1 to enable the CSIBn operation.
(5) Write transfer data to the CBnTX register (transmission start).
(6) The transmission enable interrupt request signal (INTCBnT) is received
(7) The reception complete interrupt request signal (INTCBnR) is output.
