(a) Transfer data length change function
(i) Transfer bit length = 10 bits, MSB first
(ii) Transfer bit length = 12 bits, LSB first
Preliminary User’s Manual U17566EE1V2UM00
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.
