Figure 16-7: Effect Of Transfer Data Length Setting - NEC V850E/PH2 User Manual

(a) Transfer data length function
The CSIB transfer data length can be set in 1-bit units between 8 and 16 bits using bits CBnCL3 to
CBnCL0 of the CBnCTL2 register.
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.
