16.4.5 Continuous mode (master mode, transmission mode)
Figure 16-13:
Continuous Mode (Master Mode, Transmission Mode)
MSB First (CBnDIR Bit of CBnCTL0 Register = 0),
CBnCKP Bit of the CBnCTL1 Register = 0,
CBnDAP Bit of the CBnCTL1 Register = 0,
Transfer Data Length = 8 Bits (CSnCL3 to CBnCL0 Bits of CBnCTL2 Register = 0000B)
<1> Set the CBnCTL1 and CBnCTL2 registers to specify the transfer mode.
<2> Set the CBnTXE of the CBnCTL0 register to 1 at the same time as specifying the transfer mode
using the CBnDIR bit of the CBnCTL0 register, to set the transmission/reception enabled status.
<3> Set the CBnPWR bit of the CBnCTL0 register is 1 to enable CSIB operating clock supply.
<4> Write transfer data to the CBnTX register (transmission start).
<5> The transmission enable interrupt (INTCBnT) is received and transfer data is written to the
CBnTX register.
<6> Check that the CBnTSF bit of the CBnSTR register is 0 and clear the CBnPWR bit to 0 to stop
clock supply to CSIB (end of transmission/reception).
To continue transfer, repeat steps <4> and <5> before <6>.
