The CSIBn transfer data length can be set in 1-bit units between 8 and 16 bits
using the CBnCTL2.CBnCL3 to CBnCTL2.CBnCL0 bits.
When the transfer bit length is set to a value other than 16 bits, set the data to
the CBnTX or CBnRX register starting from the LSB, regardless of whether the
transfer start bit is the MSB or LSB. Any data can be set for the higher bits that
are not used, but the receive data becomes 0 following serial transfer.
