(1) Write 00H to the CBnCTL1 register, and select communication type 1, communication clock (f
(2) Write 00H to the CBnCTL2 register, and set the transfer data length to 8 bits.
(3) Write C1H to the CBnCTL0 register, and select the transmission mode and MSB first at the same time
(4) The CBnSTR.CBnTSF bit is set to 1 by writing the transmit data to the CBnTX register, and
(5) When transmission is started, output the serial clock to the SCKBn pin, and output the transmit data
(6) When transmission of the transfer data length set with the CBnCTL2 register is completed, stop the
(7) To continue transmission, start the next transmission by writing the transmit data to the CBnTX register
(8) To end transmission, write the CBnCTL0.CBnPWR bit = 0 and the CBnCTL0.CBnTXE bit = 0.
